Stage3 Data
Lessons
Hook: The teacher holds up a bicycle and asks: 'Is this a system? What makes something a system rather than just a collection of parts?' Students turn and talk for 60 seconds before sharing out, surfacing their intuitive understanding of how parts working together create something greater than themselves.
Order: 1
Title: What Is a System? Introducing the Human Body
Targets
Key concept — Systems: students begin constructing a definition of 'system' as components that interact to perform a shared function, directly addressing the unit's key concept.
Factual inquiry question — 'What are the main organs and functions of the digestive, circulatory, respiratory, and musculoskeletal systems?': the gallery walk and body-mapping activity introduce the four systems students will investigate throughout the unit.
Conceptual inquiry question — 'How do the functions of individual organs contribute to the overall function of a body system?': the systems-hunt discussion establishes the foundational idea that parts have specialized roles within a larger whole.
Statement of Inquiry — 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being': the personal reflection activity explicitly connects the unit's central claim to students' own physical experience.
Global context — 'Health, well-being, and lifestyle: how the body's interconnected systems sustain physical health and how personal choices affect systemic balance': the personal experience journal entry situates body systems within the context of students' own identities and daily lives.
ATL skill — 'Keep and use a record of learning (science notebook / lab journal)': students make their first structured journal entries, establishing the organizational habit that will be maintained throughout the unit.
Lesson Id: L1
Objective: Students can define the concept of a 'system' and identify the four major body systems they will investigate, connecting the key concept to their own physical experience.
Activities
Whole-class 'systems hunt': students spend 3 minutes listing as many systems as they can think of from everyday life (e.g., school timetable, plumbing, solar system, traffic lights), then pairs share and the class co-constructs a working definition of 'system' — components + interactions + shared function — recorded in science journals.
Body-mapping provocation: each student traces one hand on a sticky note and writes one thing their body did in the last 24 hours (ran, digested lunch, breathed during sleep). Notes are clustered on the board into four unlabeled groups; the teacher facilitates discussion until students name the four systems — digestive, circulatory, respiratory, musculoskeletal — and articulate why they belong together.
Four-corners gallery walk: four large posters around the room each show a silhouette of the human body with one system's organs lightly illustrated but unlabeled. Student pairs rotate, writing on sticky notes what they already know, what they notice, and one question they have. The teacher uses responses to establish a class 'wonder wall' of inquiry questions for the unit.
Connecting to self — personal experience reflection: students write a 2–3 sentence journal entry responding to the prompt 'Describe a moment when you felt your body working hard — what did you notice happening inside you?' This anchors the key concept of Systems to lived physical experience and previews the Statement of Inquiry.
Closing synthesis: the teacher reveals the Statement of Inquiry — 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being' — and students annotate it in their journals, circling words they understand and underlining words they want to explore further, setting a personal learning intention for the unit.
Teacher Notes: A common misconception at this stage is that body systems are entirely separate and independent — students often think of the heart as 'just a pump' with no connection to digestion or movement. Avoid correcting this prematurely; instead, use the wonder wall questions to note where students already sense connections, and return to those observations explicitly in L6 (Systems in Concert). For students who struggle with abstract definitions, anchor the concept of 'system' in the concrete bicycle or school-timetable examples before asking them to apply it to the body.
Prior Knowledge
No prior lessons in this sequence have been taught; this is the opening lesson. Students should bring general familiarity with the human body from primary/elementary science and personal lived experience of physical activity and bodily sensations.
Duration Minutes: 45
Hook: The teacher holds up a piece of bread and asks: 'This sandwich will become part of your muscles, your blood, your bones — how does a solid chunk of food become YOU?' Students do a 30-second Think-Pair-Share predicting what the body must do to food before it can be used.
Order: 2
Title: Fueling the Body: Structure and Function of the Digestive System
Targets
Factual inquiry question: 'What are the main organs and functions of the digestive, circulatory, respiratory, and musculoskeletal systems?' — this lesson directly addresses the digestive system component.
Conceptual inquiry question: 'How do the functions of individual organs contribute to the overall function of a body system?' — students trace how each organ's specific role (e.g., stomach churning, villi absorbing) contributes to the digestive system's overall goal of nutrient delivery.
Criterion A – Knowing and Understanding (strands i and ii): accurate recall of digestive organ structures and functions; correct use of scientific terminology including peristalsis, enzyme, bile, villi, and absorption.
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being' — the digestive system is the first specialized system examined in depth.
Unit content: 'Structure and function of the digestive system: organs, mechanical and chemical digestion, nutrient absorption.'
ATL – Self-Management/Organization: 'Keep and use a record of learning (science notebook / lab journal)' — students record observations from both stations and annotate diagrams in their journals.
Lesson Id: L2
Objective: Students can identify the main organs of the digestive system and explain how mechanical and chemical digestion break down food for nutrient absorption.
Activities
Organ mapping warm-up: Students receive a blank outline of the human torso and, using prior intuition, sketch where they think digestive organs sit. The teacher then reveals a labeled diagram and students self-correct, annotating their outlines with organ names (mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas) — this surfaces misconceptions before instruction.
Mechanical vs. chemical digestion stations: Two short demonstration stations run simultaneously — at one, students physically tear and mash a piece of bread to model mechanical digestion; at the other, the teacher adds a drop of iodine to starch solution and then to saliva-mixed starch solution to show enzymatic (chemical) breakdown, prompting students to record observations in their science journals.
Guided note-taking with annotated diagram: Using a projected diagram, the teacher narrates the journey of a nutrient from mouth to bloodstream, pausing at each organ for students to add function labels and key vocabulary (peristalsis, enzyme, bile, villi, absorption) to their torso outlines.
Nutrient absorption modeling activity: Students use a mesh bag (representing villi) submerged in colored water (representing blood) to observe how small molecules pass through while large particles do not, then write a one-sentence explanation linking the model to the concept of absorption in the small intestine.
Exit ticket — 'Organ function card sort': Students receive six cards each naming a digestive organ and six cards each describing a function; they match them independently in the final five minutes, which the teacher collects to assess understanding and inform the next lesson.
Teacher Notes: A common misconception is that digestion happens primarily in the stomach; many students underestimate the small intestine's central role in both chemical digestion and absorption — the mesh-bag model and explicit labeling of villi are designed to address this directly. For students who struggle with the mechanical/chemical distinction, anchor the language to familiar experiences: chewing = mechanical, saliva breaking down starch = chemical, before introducing enzyme terminology.
Prior Knowledge
Students can define the concept of a 'system' as a set of interacting parts working together toward a common function (from L1).
Students have identified the four major body systems — digestive, circulatory, respiratory, and musculoskeletal — as the focus of the unit (from L1).
Students understand that the key concept of the unit is 'Systems' and that related concepts include Function, Interaction, and Balance (from L1).
Students have begun using a science journal to record observations and reflections (from L1).
Duration Minutes: 45
Hook: The teacher projects a 10-second clip of a human heartbeat on an ultrasound and asks students to place two fingers on their wrist or neck to feel their own pulse, then poses the question: 'In one minute, your heart beats roughly 70 times — what exactly is it pumping, where is it going, and why does it never stop?'
Order: 3
Title: Pumping Life: Structure and Function of the Circulatory System
Targets
Factual inquiry question: 'How does the circulatory system transport oxygen and nutrients to cells throughout the body?'
Factual inquiry question: 'What are the main organs and functions of the digestive, circulatory, respiratory, and musculoskeletal systems?' — addressed here for the circulatory system
Unit content: 'Structure and function of the circulatory system: heart, blood vessels, blood components, and circulation pathways'
Criterion A – Knowing and Understanding (strand i): recall and explain the structures and functions of the circulatory system; (strand ii): use scientific terminology accurately (e.g., atrium, ventricle, artery, vein, capillary, pulmonary circuit, systemic circuit)
ATL skill – Keep and use a record of learning (science notebook / lab journal): students record the annotated diagram, card-sort conclusions, and the exit-ticket sketch in their journal
Related concept – Function: how the specialized structures of the heart and blood vessels carry out the function of transporting materials throughout the body
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being' — grounded here in the circulatory system's specialized transport function
Lesson Id: L3
Objective: Students can describe the structure of the heart, blood vessels, and blood components, and trace the pathway of circulation through the body.
Activities
Pulse check and class data collection (5 min): Students count their resting heart rate for 30 seconds, double it, and record it in their science journal; the teacher plots a quick class dot plot on the board to surface natural variation and spark curiosity about what controls heart rate.
Guided diagram annotation — heart structure (10 min): Students receive a blank outline diagram of the heart and, using a colour-coded key, label the four chambers (right/left atria and ventricles), four valves, and the major vessels (aorta, pulmonary artery/vein, vena cava) while the teacher uses a projected 3-D model or animation to narrate blood flow step by step.
Tracing the double circulation pathway (8 min): Working in pairs, students use arrows to draw and annotate the pulmonary circuit (heart → lungs → heart) and the systemic circuit (heart → body → heart) on their diagram, explicitly labelling where blood is oxygenated and deoxygenated, and identifying the vessels as arteries, veins, or capillaries.
Blood components card sort (7 min): Small groups receive a set of cards describing red blood cells, white blood cells, platelets, and plasma; they match each component to its function and then sequence the cards to explain how each component contributes to the circulatory system's overall role in transport, defence, and clotting.
Modelling circulation with a kinesthetic walk (8 min): Using labelled stations around the room (right atrium, lungs, left ventricle, muscle tissue, small intestine), students physically walk the path of a red blood cell, picking up an 'oxygen token' at the lungs and dropping it at the tissue station, reinforcing the sequence of circulation and the link to the digestive system introduced in L2.
Exit ticket — science journal (7 min): Students sketch the double circulation pathway from memory, label at least five structures with correct scientific terminology, and write one sentence answering: 'How does the structure of the heart allow it to pump blood through two separate circuits at the same time?'
Teacher Notes: A common misconception is that arteries always carry oxygenated blood and veins always carry deoxygenated blood; explicitly flag the pulmonary artery (deoxygenated) and pulmonary vein (oxygenated) as exceptions during the diagram activity. For students who struggle with spatial reasoning around the heart diagram, provide a pre-labelled reference card they can use during the kinesthetic walk so cognitive load is distributed and all students can participate in tracing the full circulation pathway.
Prior Knowledge
Definition of a 'system' and the idea that body systems have specialized structures that perform specific functions (L1)
Understanding that nutrients absorbed by the digestive system must be transported to body cells — students know food is broken down in the digestive system but have not yet explored how nutrients travel onward (L2)
Familiarity with the science journal as a record-keeping tool and the expectation of recording observations and reflections after each activity (L1, L2)
Duration Minutes: 45
Hook: Ask students to take a slow, deep breath and hold it for 5 seconds, then exhale fully. Pose the question: 'Where exactly did that oxygen go, and what came back out—and why does your body need to make that swap millions of times a day?'
Order: 4
Title: Every Breath You Take: Structure and Function of the Respiratory System
Targets
Factual inquiry question: 'What are the main organs and functions of the digestive, circulatory, respiratory, and musculoskeletal systems?' — this lesson addresses the respiratory system component
Factual inquiry question: 'How does the circulatory system transport oxygen and nutrients to cells throughout the body?' — gas exchange at the alveoli is the point where the respiratory system hands oxygen to the circulatory system
Conceptual inquiry question: 'How do the functions of individual organs contribute to the overall function of a body system?' — students analyze how each airway structure and the alveolus contribute to the respiratory system's overall gas-exchange function
Related concept – Function: students explain how structural features of the alveoli (thin walls, large surface area, moist lining, capillary network) are directly linked to their gas-exchange function
Related concept – Interaction: the lesson establishes the respiratory–circulatory interface at the alveolus, laying groundwork for system interaction discussions in L6
Unit content strand: 'Structure and function of the respiratory system: airways, lungs, gas exchange at the alveoli'
ATL skill – Keep and use a record of learning (science notebook / lab journal): students record labeled diagrams, structural adaptations, role-play sketches, and the exit-task explanation in their ongoing science journal
Lesson Id: L4
Objective: Students can explain the structure of the airways and lungs and describe how gas exchange occurs at the alveoli to supply oxygen and remove carbon dioxide.
Activities
Guided diagram labeling: Students receive a blank outline diagram of the respiratory system (nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, diaphragm) and, using a short teacher-led narration of 'the journey of one breath,' label each structure and annotate its function in their science journal.
Alveoli close-up: Teacher displays a magnified image of alveolar clusters alongside a capillary network, then leads a class discussion using think-pair-share on why the alveoli's features—thin walls, moist surface, large surface area, rich blood supply—make them ideal for gas exchange. Students record three structural adaptations and link each to its function.
Gas exchange role-play: Small groups of four act out diffusion at the alveolus—two students represent oxygen molecules moving from high to low concentration into the blood, two represent carbon dioxide moving out—while the class observes and identifies the driving force (concentration gradient). Groups then sketch and annotate the exchange in their journals.
Breathing mechanics mini-demonstration: Using a bell-jar lung model (or a teacher-made model with a plastic bottle, balloons, and a rubber sheet), students observe how diaphragm contraction and relaxation changes thoracic volume and drives inhalation and exhalation, connecting mechanics to function.
Exit task – 'Explain the swap': Students write three sentences in their science journal answering: 'Trace the path of one oxygen molecule from the air outside to a red blood cell, and explain why carbon dioxide travels in the opposite direction.' Teacher collects journals briefly to check for accuracy before the next lesson.
Teacher Notes: A common misconception is that we breathe in pure oxygen and breathe out pure carbon dioxide; clarify that inhaled air is ~21% O₂ and exhaled air still contains ~16% O₂, with CO₂ rising from ~0.04% to ~4%—the exchange is partial, not total. For students who struggle with diffusion, explicitly revisit the concept of concentration gradient using a simple analogy (perfume spreading across a room) before the role-play activity.
Prior Knowledge
Definition of a 'system' and understanding that body systems have specialized structures performing specific functions (L1)
How the digestive system absorbs nutrients that must be transported to cells (L2)
How the circulatory system—heart, blood vessels, and blood components—transports substances around the body, including the concept that blood picks up and delivers materials (L3)
Basic cell-level understanding that cells need oxygen and produce carbon dioxide as a waste product (introduced in L3 context)
Duration Minutes: 45
Hook: The teacher asks students to stand up, bend their elbow, and feel the back of their upper arm tighten while the front relaxes — then asks: 'What just happened inside your arm, and how many different structures had to work together to make that simple movement possible?'
Order: 5
Title: Bones, Joints, and Muscles: The Musculoskeletal System in Action
Targets
Unit content: 'Structure and function of the musculoskeletal system: bones, joints, muscles, and movement mechanics'
Factual inquiry question: 'What are the main organs and functions of the digestive, circulatory, respiratory, and musculoskeletal systems?'
Conceptual inquiry question: 'How do the functions of individual organs contribute to the overall function of a body system?'
Related concept – Function: students identify the specific roles each musculoskeletal component (bone, joint, muscle) plays within the system
Related concept – Interaction: students explain how bones, joints, and muscles must act together to produce movement, previewing the system-interaction focus of L6
ATL skill – 'Keep and use a record of learning (science notebook / lab journal)': students record observations from the lever model activity and write analytical exit reflections in their journal
Criterion A – Knowing and Understanding (strand i): recall and explain structures and functions of the musculoskeletal system; (strand ii): use scientific terminology accurately (e.g., antagonistic muscles, hinge joint, tendon, ligament)
Lesson Id: L5
Objective: Students can identify the roles of bones, joints, and muscles and explain how they work together to produce movement.
Activities
Guided 'body mapping' warm-up: students sketch a simple outline of the human body and label where they think bones, joints, and muscles are located, then share with a partner before the teacher reveals a labeled diagram to surface prior knowledge and correct misconceptions.
Direct instruction with annotated diagrams: teacher introduces the three main roles of the skeleton (support, protection, movement), the types of joints (hinge, ball-and-socket, pivot, fixed) with real-life examples, and the concept of antagonistic muscle pairs (e.g., biceps/triceps), using clear scientific vocabulary.
Hands-on model activity: student pairs use a simple lever model (ruler, rubber bands, and a pivot point) or their own forearm to simulate how bones act as levers, muscles provide force, and joints act as fulcrums — recording observations in their science journal.
Collaborative jigsaw: small groups are each assigned one structural component (bones, cartilage, tendons/ligaments, muscles) and create a brief explanation card; groups then reassemble to teach each other how all components integrate to produce a single movement such as kicking a ball.
Exit analysis: teacher displays an image of a gymnast in a complex pose and students write two to three sentences in their science journal explaining which types of joints and muscle actions are involved, using at least three scientific terms introduced in the lesson.
Teacher Notes: A common misconception is that muscles both push and pull — students often think muscles can actively extend as well as contract; emphasize that muscles only pull (contract) and that movement in the opposite direction requires the antagonistic muscle to contract. For students who struggle with abstract lever mechanics, having them physically perform the elbow flexion/extension while touching the biceps and triceps simultaneously provides a concrete kinesthetic anchor before introducing diagrams.
Prior Knowledge
Definition of a 'system' and how organs within a system carry out specialized functions (from L1)
Understanding that body systems are made up of interacting structures with distinct roles (from L1–L4)
Basic familiarity with how the digestive, circulatory, and respiratory systems each have specialized organs — providing a framework for recognizing the musculoskeletal system as a fourth major system
Practice using scientific terminology to describe organ structure and function (from L2–L4)
Habit of recording observations and vocabulary in a science journal (established in prior lessons)
Duration Minutes: 45
Hook: The teacher asks students to stand up and do 30 seconds of jumping jacks, then immediately sit down and answer: 'Write down every body system you just used and what it was doing — you have 60 seconds.' Students share responses and the class notices how many systems fired simultaneously.
Order: 6
Title: Systems in Concert: How Body Systems Interact During Physical Activity
Targets
Content: 'Interactions between systems: how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during physical activity'
Related concept – Interaction: 'In what ways do body systems interact so that a change in one system affects the others?'
Related concept – Function: 'How do the functions of individual organs contribute to the overall function of a body system?'
Inquiry question (conceptual): 'In what ways do body systems interact so that a change in one system affects the others?'
Criterion A – Knowing and Understanding strand ii: 'use scientific terminology accurately' to describe system interactions during exercise
ATL – Keep and use a record of learning (science notebook / lab journal): students add annotated diagrams and flow maps to their science journals as a record of system interaction understanding
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being'
Lesson Id: L6
Objective: Students can explain how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during exercise, using accurate scientific terminology to describe system interactions.
Activities
Whole-class debrief of the jumping jacks experience: teacher uses targeted questioning to draw out observations about faster heartbeat, heavier breathing, muscle fatigue, and energy use, recording student responses on the board under each of the four system headings (circulatory, respiratory, digestive, musculoskeletal).
Guided note-taking and annotated diagram activity: students receive a blank body outline and, working through a teacher-led explanation, label and annotate how each system contributes during exercise — muscles demand oxygen and glucose; the circulatory system increases heart rate and redirects blood flow; the respiratory system increases breathing rate for greater gas exchange at the alveoli; the digestive system supplies previously absorbed glucose as fuel.
Systems interaction mapping: in pairs, students create a cause-and-effect flow diagram starting with the prompt 'Muscles begin to contract' and trace the cascade of responses across all four systems, using arrows and scientific vocabulary (e.g., vasodilation, cardiac output, tidal volume, glycogen, peristalsis) to show how a change in one system triggers responses in others.
Scenario challenge cards: small groups receive a scenario card (e.g., 'A student runs a 400 m race,' 'A dancer performs a five-minute routine,' 'A person carries heavy groceries up three flights of stairs') and must explain in writing and verbally to the class which systems are activated, how they interact, and what would happen if one system could not respond adequately.
Exit ticket: students individually write a three-sentence explanation answering the conceptual inquiry question 'In what ways do body systems interact so that a change in one system affects the others?' using at least three pieces of accurate scientific terminology from the lesson.
Teacher Notes: A common misconception is that body systems operate independently and only 'turn on' one at a time during activity — students often underestimate the digestive system's role during exercise (stored glucose from digestion fuels muscles) and may not connect prior nutrient absorption learning to this lesson; explicitly bridging back to L2 helps. For students who struggle with the flow diagram, provide a partially completed scaffold with the first two arrows filled in and a word bank of scientific vocabulary to reduce cognitive load.

Title: Staying in Balance: Introduction to Homeostasis
Targets
Unit content: 'Homeostasis and balance: the concept of the body maintaining stable internal conditions (e.g., blood glucose regulation, body temperature)'
Unit content: 'Interactions between systems: how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during physical activity' — extended here to show how cooperation serves homeostatic balance
Conceptual inquiry question: 'What does 'balance' mean at the level of the human body, and how do systems work together to maintain it?'
Conceptual inquiry question: 'In what ways do body systems interact so that a change in one system affects the others?'
Related concept — Balance: illustrated through the feedback loop model showing how the body detects and corrects deviations from a set point
Related concept — Interaction: demonstrated by tracing how multiple systems (circulatory, endocrine, nervous) participate in a single homeostatic response
ATL skill: 'Keep and use a record of learning (science notebook / lab journal)' — students annotate diagrams, map case studies, and complete an exit ticket in their journals
Criterion A – Knowing and Understanding: students use scientific terminology accurately (homeostasis, stimulus, receptor, effector, feedback) and explain how body systems maintain stable internal conditions
Lesson Id: L7
Objective: Students can define homeostasis and use examples such as blood glucose regulation and body temperature control to explain how the body maintains stable internal conditions.
Activities
Whole-class discussion (5 min): Students share prior observations of the body 'correcting itself' (sweating when hot, shivering when cold, feeling hungry, getting thirsty) — teacher records responses on the board and introduces the term 'homeostasis' as the body's ability to maintain a stable internal environment despite external changes.
Direct instruction with annotated diagram (8 min): Teacher presents a simple feedback loop model (stimulus → receptor → control centre → effector → response) using body temperature regulation as the worked example, explicitly labeling how sweating and shivering act as corrective responses; students copy and annotate the diagram in their science journals.
Paired case-study analysis (10 min): Each pair receives one of two scenario cards — (A) blood glucose regulation after eating a meal (insulin release, glucose uptake by cells) or (B) water balance regulation during exercise (thirst, kidney response) — and maps their scenario onto the same feedback loop framework, identifying stimulus, receptor, control centre, effector, and response.
Gallery share and class comparison (7 min): One pair from each scenario briefly presents their feedback loop to the class; teacher facilitates comparison, highlighting that all homeostatic mechanisms follow the same underlying pattern regardless of the variable being regulated.
Connection to prior systems (8 min): Students revisit their science journal notes from L3 (circulatory), L4 (respiratory), and L6 (systems interaction) and identify at least one way each system contributes to maintaining homeostasis (e.g., heart rate adjusting to deliver more oxygen, breathing rate changing to regulate CO2 levels), recording connections in a simple table.
Exit ticket (7 min): Students write a 3-sentence response in their science journal answering: 'Define homeostasis in your own words, give one example from today, and explain which body system is most involved in your example and why.'
Teacher Notes: A common misconception is that homeostasis means the body keeps conditions perfectly constant — clarify that it means conditions are kept within a narrow, acceptable range through continuous adjustment, not that they are fixed. For students who struggle with the abstract feedback loop, use a concrete analogy such as a home heating system (thermostat detects cold → furnace switches on → room warms → thermostat detects warmth → furnace switches off) before applying the model to biological examples.

Hook: The teacher displays two contrasting photos side by side on the board: one of a person resting on a sofa and one of the same person sprinting. Students are asked to silently write down three things they predict are different inside the body in each scenario — then share with a partner before a brief whole-class share-out to surface prior intuitions about measurable physiological changes.
Order: 8
Title: Designing Our Investigation: Measuring the Effect of Exercise on Body Systems
Targets
Criterion B – Inquiring and Designing (strands i, ii, iii): 'Students design a controlled investigation—such as measuring the effect of physical activity on heart rate and breathing rate—requiring them to identify a focused problem, formulate a testable hypothesis linking two body systems, and plan a method with appropriate variables and controls.'
Factual inquiry question: 'What measurable indicators (e.g., heart rate, breathing rate) reflect the current state of body system balance?'
Conceptual inquiry question: 'In what ways do body systems interact so that a change in one system affects the others?'
ATL – Thinking/Critical Thinking: 'Draw reasonable conclusions and generalizations from evidence' — scaffolded here by ensuring the hypothesis is evidence-linked before data collection begins.
ATL – Self-Management/Organization Skills: 'Keep and use a record of learning (science notebook / lab journal)' — students record their hypothesis, variables, and method in their science journals.
Related concept – Interaction: students must articulate in their hypothesis how a change in physical activity triggers responses across the circulatory and respiratory systems.
Related concept – Balance: students connect the investigation design to the idea that measurable physiological variables (heart rate, breathing rate) are indicators of the body's homeostatic state.
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being' — the investigation design grounds this abstract statement in a concrete, student-designed inquiry.
Lesson Id: L8
Objective: Students can formulate a testable hypothesis and design a controlled investigation—identifying variables and controls—to measure how physical activity affects heart rate and breathing rate.
Activities
Whole-class mini-lesson (5 min): Teacher introduces the vocabulary of scientific investigation — independent variable, dependent variable, controlled variables, hypothesis — using a simple anchor chart. Students add these terms to their science journals with brief definitions in their own words.
Guided hypothesis writing (8 min): Using a structured sentence frame ('If [independent variable] increases, then [dependent variable] will [increase/decrease] because [scientific reasoning linking circulatory and respiratory systems]...'), student pairs draft a testable hypothesis connecting exercise intensity to heart rate and/or breathing rate. Two or three pairs share aloud; teacher annotates examples on the board to model scientific precision.
Investigation design workshop (12 min): Small groups receive a planning template listing the headings: Research Question, Hypothesis, Independent Variable, Dependent Variables, Controlled Variables, Materials, Step-by-Step Method, Safety Considerations. Groups collaboratively complete the template, deciding on the type and duration of exercise, how they will measure heart rate and breathing rate (manual pulse count, stopwatch), how many trials to run, and what they will keep constant (same person, same time of day, same measurement technique).
Gallery critique (8 min): Groups post their planning templates on the wall. Students do a silent gallery walk, leaving one sticky-note comment per plan using the prompt 'One strength / One question' to identify whether variables are clearly defined, controls are sufficient, and the method is repeatable. Groups then return to their own plan and revise based on feedback.
Whole-class debrief and consolidation (7 min): Teacher facilitates a discussion asking 'What makes this a fair test?' and 'How does your hypothesis connect to what we know about how the circulatory and respiratory systems interact?' Students record a refined final hypothesis and any method revisions in their science journals, noting how the design links to the concept of system interaction.
Exit ticket (5 min): Each student independently writes one controlled variable they identified and explains in one sentence why keeping it constant is important for the reliability of the investigation.
Teacher Notes: A common misconception is that heart rate and breathing rate change independently of each other; prompt students to explicitly link the two systems in their hypothesis by asking 'Why would the body need more oxygen delivered AND more carbon dioxide removed at the same time?' For students who struggle with the planning template, provide a partially completed exemplar that shows one variable correctly identified but leaves the remaining rows blank for them to complete, rather than offering a fully worked model.
Prior Knowledge
Students can describe the structure of the heart, blood vessels, and blood components, and trace the pathway of circulation (L3).
Students can explain how gas exchange occurs at the alveoli to supply oxygen and remove carbon dioxide (L4).
Students can explain how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during exercise, using accurate scientific terminology to describe system interactions (L6).
Students can define homeostasis and explain how the body maintains stable internal conditions such as blood glucose and body temperature (L7).
Students maintain a structured science journal in which they record observations, hypotheses, and reflections (ATL – Organization Skills, established throughout prior lessons).
Duration Minutes: 45
Hook: The teacher projects a messy, handwritten table of jumbled numbers on the board and asks: 'A scientist collected this data during an experiment — can you tell me anything useful from it?' Students quickly discover that raw, unorganized data is nearly meaningless, setting up the purpose of today's lesson: turning real measurements into clear, interpretable evidence.
Order: 9
Title: Collecting and Processing Data: Running Our Physical Activity Investigation
Targets
Criterion C – Processing and Evaluating (strands i, ii): 'Students collect, record, and process data from their body-systems investigation, interpret results in terms of system interaction and balance.'
ATL – Self-Management/Organization: 'Keep and use a record of learning (science notebook / lab journal)' — students record observations, data tables, and reflections after each inquiry activity, tracking how their understanding of system interactions develops over time.
ATL – Thinking/Critical Thinking: 'Draw reasonable conclusions and generalizations from evidence' — students analyze graphs and tables to draw conclusions about how the circulatory and respiratory systems interact under stress, justifying their claims with specific data points.
Factual inquiry question: 'What measurable indicators (e.g., heart rate, breathing rate) reflect the current state of body system balance?'
Conceptual inquiry question: 'In what ways do body systems interact so that a change in one system affects the others?'
Unit content: 'Interactions between systems: how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during physical activity' and 'Scientific inquiry skills: designing a fair test, measuring physiological variables, processing and evaluating experimental data.'
Lesson Id: L9
Objective: Students can collect, record, and process physiological data from their investigation, organizing results in tables and graphs to reveal patterns in system response.
Activities
Safety briefing and equipment check (2 min): Teacher reviews safe exercise protocols, confirms student health considerations, and distributes data collection sheets, stopwatches, and any pulse oximeters or heart rate monitors available; students retrieve their investigation designs from their science journals (L8).
Baseline data collection (5 min): Students measure and record their resting heart rate (beats per minute) and resting breathing rate (breaths per minute) for two minutes while seated, repeating the measurement twice to obtain an average — reinforcing the importance of repeated trials from their L8 design.
Physical activity trials (15 min): Student pairs take turns performing the agreed exercise (e.g., stepping, jogging in place) at the intensity and duration specified in their L8 method; the partner records heart rate and breathing rate immediately post-exercise and again after 1, 3, and 5 minutes of recovery, capturing the response and recovery curve.
Data table construction (8 min): Students transfer all raw measurements into a structured data table in their science journal, using column headers that include units (bpm, breaths/min), time points, and trial numbers; teacher circulates to check for correct units, consistent significant figures, and completeness.
Graph construction and pattern identification (10 min): Students plot their processed data as a line graph (time on x-axis, rate on y-axis) with clearly labelled axes, a title, and a key distinguishing heart rate from breathing rate; they annotate the graph with an arrow marking the transition from exercise to recovery and write one sentence describing the pattern they observe.
Exit reflection in science journal (5 min): Students respond to the prompt: 'What pattern do your graphs show, and what does it suggest about how the circulatory and respiratory systems respond to physical activity?' — priming them for the conclusion-drawing work in L10.
Teacher Notes: A common misconception is that heart rate and breathing rate increase proportionally and simultaneously — students may be surprised that breathing rate recovery lags slightly behind heart rate; prompt them to think about why CO2 removal might drive continued elevated breathing. For students who cannot participate in physical activity, assign them the role of data recorder and timer for their partner, then provide them with the class's pooled dataset to process and graph, ensuring full participation in the data-handling objective.
Prior Knowledge
Students have formulated a testable hypothesis linking physical activity to changes in heart rate and breathing rate (L8).
Students have identified independent, dependent, and controlled variables and planned a step-by-step method with repeated trials and controls (L8).
Students can describe how the circulatory system transports oxygen and nutrients (L3) and how gas exchange in the alveoli supplies oxygen and removes carbon dioxide (L4).
Students can explain how the circulatory, respiratory, and musculoskeletal systems cooperate during exercise (L6).
Students have been maintaining a structured science journal throughout the unit and are familiar with recording observations, hypotheses, and data in it (ATL – Organization Skills).
Duration Minutes: 45
Hook: Display two anonymous student data sets from L9 on the board—one showing a clear trend and one showing inconsistent results—and ask: 'Both groups followed the same method. Why might their conclusions be different? Which group's results should we trust more?'
Order: 10
Title: Drawing Conclusions: Evaluating Evidence from Our Investigation
Targets
Inquiry question (factual): 'What measurable indicators (e.g., heart rate, breathing rate) reflect the current state of body system balance?' — students interpret their own data to answer this directly.
Inquiry question (conceptual): 'In what ways do body systems interact so that a change in one system affects the others?' — students use experimental evidence to explain the circulatory–respiratory feedback loop under exercise stress.
MYP Criterion C – Processing and Evaluating (strands i, ii, iii, iv): students collect, record, and process data; interpret results in terms of system interaction and balance; evaluate the reliability of their method; and suggest improvements.
ATL Skill – 'Draw reasonable conclusions and generalizations from evidence': students analyze graphs and tables to draw conclusions about how the circulatory and respiratory systems interact under stress, justifying their claims with specific data points.
ATL Skill – 'Keep and use a record of learning (science notebook / lab journal)': students record conclusions, limitation analyses, and improvement suggestions in their structured science journals.
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being' — students connect experimental evidence of system interaction to this overarching idea.
Unit content: 'Interactions between systems: how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during physical activity' and 'Scientific inquiry skills: designing a fair test, measuring physiological variables, processing and evaluating experimental data.'
Lesson Id: L10
Objective: Students can interpret their experimental results to draw evidence-based conclusions about circulatory and respiratory system interactions, and evaluate the reliability and limitations of their method.
Activities
Whole-class data comparison (8 min): Project a shared class data table aggregating all groups' heart rate and breathing rate results from L9; students identify the range of values, spot outliers, and discuss whether the class data shows a consistent pattern, recording observations in their science journals.
Guided graph interpretation (10 min): In pairs, students annotate their own graphs from L9 by labeling the trend line, identifying the point of greatest change, and writing one sentence explaining what the pattern shows about how the circulatory and respiratory systems respond to increasing exercise intensity—using terms such as 'oxygen demand,' 'cardiac output,' and 'gas exchange.'
Evidence-based conclusion writing (10 min): Individually, students draft a structured conclusion using a scaffold (Claim → Evidence → Reasoning): they state whether their hypothesis was supported, cite at least two specific data points as evidence, and explain the biological mechanism linking heart rate and breathing rate changes to system interaction and homeostatic demand.
Method evaluation discussion (8 min): Small groups identify at least two sources of error or limitation in their investigation (e.g., timing accuracy, variation in exercise intensity between students, sample size) and suggest one concrete improvement for each, recording findings in their journals under the heading 'Reliability and Limitations.'
Class debrief and connection to summative (9 min): Teacher facilitates a brief whole-class share-out where groups report one limitation and one improvement; teacher explicitly connects the skill of evaluating evidence reliability to the upcoming public health campaign, asking: 'If you were making a health recommendation based on this data, what caveats would you need to include?'
Teacher Notes: A common misconception is that heart rate and breathing rate increase independently and for separate reasons; scaffold students to see these as coupled responses driven by a shared trigger (increased cellular oxygen demand and CO2 buildup), reinforcing the 'Interaction' related concept. For students who struggle with the Claim–Evidence–Reasoning structure, provide a sentence-starter frame and model one complete example using class data before independent writing begins.
Prior Knowledge
Students have collected, recorded, and organized heart rate and breathing rate data in tables and graphs during L9, so raw data and visual representations are already prepared.
Students can explain how the circulatory and respiratory systems interact during physical activity, including the roles of oxygen delivery, carbon dioxide removal, and cardiac output (from L6).
Students understand the concept of homeostasis and how the body responds to increased physiological demand (from L7).
Students have formulated a testable hypothesis and identified independent, dependent, and controlled variables for this investigation (from L8), giving them a reference point for evaluating whether their method controlled for confounding factors.
Students are familiar with the science journal as an organizational tool and have been recording observations and data throughout the unit.
Duration Minutes: 45
Hook: Display a split-screen image: a healthy, clear alveolus beside a tar-coated smoker's alveolus, and a healthy artery beside one narrowed by plaque. Ask students: 'What do you notice? What body systems are affected — and does the disruption stop there?'
Order: 11
Title: When Systems Break Down: Lifestyle Choices, Disease, and Systemic Disruption
Targets
Content: 'Impacts of lifestyle choices and disease on body system function and balance (e.g., diet, exercise, smoking, diabetes, asthma)'
Content: 'Interactions between systems: how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during physical activity' — extended here to disrupted cooperation under disease or harmful lifestyle conditions.
Content: 'Homeostasis and balance: the concept of the body maintaining stable internal conditions (e.g., blood glucose regulation, body temperature)' — examined through the lens of what happens when balance is lost.
Criterion A rationale: 'application of knowledge to explain how lifestyle factors or diseases disrupt systemic balance' — students apply system knowledge to novel disease/lifestyle scenarios.
Inquiry question (conceptual): 'In what ways do body systems interact so that a change in one system affects the others?' — directly explored through cascade mapping.
Inquiry question (debatable): 'To what extent are individuals responsible for maintaining the balance of their own body systems through lifestyle choices?' — surfaced in discussion and journal reflection.
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being.' — students begin connecting disruption knowledge to informed decision-making.
ATL – Self-Management – Organization Skills: 'Students maintain a structured science journal throughout the unit, recording observations, hypothesis revisions, data tables, and reflections after each inquiry activity' — reinforced through the structured journal entry.
Lesson Id: L11
Objective: Students can explain how lifestyle factors such as diet, exercise, and smoking, and diseases such as type 2 diabetes and asthma, disrupt body system function and cascade across interconnected systems.
Activities
Whole-class discussion (5 min): Students share observations from the hook images, identifying which systems are visibly affected and predicting whether other systems might also be impacted — teacher records predictions on the board as a 'cascade map' to revisit at the end.
Direct instruction with annotated diagram (8 min): Teacher walks through two case studies — type 2 diabetes (disruption of blood glucose regulation, impact on circulatory, digestive, and musculoskeletal systems) and asthma (narrowed airways, impact on respiratory and circulatory systems and exercise capacity) — modeling how to trace a disruption from one system into interconnected systems using precise terminology (e.g., insulin resistance, bronchoconstriction, reduced gas exchange).
Cascade-mapping activity (12 min): In pairs, students receive a card describing a lifestyle factor or disease (options: chronic sedentary behavior, high-fat diet, smoking, type 2 diabetes, asthma). Using a blank 'systems interaction' template showing the four body systems as linked nodes, they map how their assigned disruption originates in one system and cascades into at least two others, annotating each arrow with a specific physiological consequence.
Gallery walk and peer challenge (8 min): Pairs post their cascade maps around the room. Students rotate, add a sticky note to one map either confirming a connection with a scientific explanation or respectfully challenging a link they think is inaccurate or unsupported — encouraging critical engagement with peers' reasoning.
Science journal reflection (7 min): Students individually write a structured response in their science journal: 'Choose one disruption from today. Explain how it affects at least two body systems and describe one measurable indicator (e.g., heart rate, blood glucose level) that would show the system is out of balance.' Teacher circulates to check for accurate use of terminology such as homeostasis, cascade, and systemic.
Closing synthesis (5 min): Teacher returns to the opening board predictions, asks students to confirm, revise, or extend their initial cascade ideas, and explicitly links the lesson to the summative campaign: 'The disruption you mapped today is exactly the story your public health campaign will need to tell — clearly, accurately, and for a real audience.'
Teacher Notes: A common misconception is that a disease 'belongs to' only one system (e.g., asthma is only a lung problem); scaffold students to see that reduced gas exchange immediately stresses the circulatory system and limits musculoskeletal performance, making the cascade explicit and inevitable. For students who struggle to initiate cascade mapping, provide a sentence stem: 'Because [organ/system] cannot [function], the [second system] must/cannot [response], which means [measurable consequence]' — this structure also prepares them for the analytical writing required in the summative campaign.
Prior Knowledge
Students can define homeostasis and explain how the body uses feedback mechanisms to maintain stable internal conditions such as blood glucose levels and body temperature (L7).
Students can explain how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during physical activity and describe the consequences when one system is stressed (L6).
Students can identify the structures and functions of all four major body systems — digestive, circulatory, respiratory, and musculoskeletal (L2–L5).
Students have collected and interpreted physiological data (heart rate, breathing rate) and can connect measurable indicators to system function and balance (L9–L10).
Students are familiar with the related concepts of Function, Interaction, and Balance as lenses for analyzing body system behavior.
Duration Minutes: 45
Hook: Display three 'facts' about type 2 diabetes—one from a peer-reviewed journal abstract, one from the WHO website, and one from a wellness influencer's Instagram post—and ask students: 'Which of these would you trust to put in a public health campaign, and why?' Give students 60 seconds to silently rank them before taking a quick show-of-hands poll.
Order: 12
Title: Finding Credible Evidence: Evaluating Sources for the Campaign
Targets
ATL – Research/Information Literacy: 'Access information to be informed and inform others; evaluate the credibility of sources' — specifically the learning experience of comparing peer-reviewed sources, health organization websites, and popular media, and 'explicitly evaluating each source's reliability and potential bias before incorporating evidence into their analysis.'
Summative target: 'ATL – Information Literacy: evaluating credibility and bias of sources used to support campaign claims'
Inquiry question (debatable): 'To what extent are individuals responsible for maintaining the balance of their own body systems through lifestyle choices?' — source evaluation skills are necessary for students to find credible evidence that informs this debate.
Summative target: 'Criterion D – Reflecting on the Impacts of Science (strands i, ii, iii): evaluation of how scientific understanding of body systems informs public health recommendations' — students must ground their campaign's public health recommendations in credible, evaluated evidence.
Unit content: 'Impacts of lifestyle choices and disease on body system function and balance (e.g., diet, exercise, smoking, diabetes, asthma)' — students are selecting reliable sources specifically about these impacts to use in their campaigns.
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being' — evaluating sources is a prerequisite for the informed, evidence-based communication the campaign requires.
Lesson Id: L12
Objective: Students can compare and evaluate the credibility and potential bias of peer-reviewed, health organization, and popular media sources to select reliable evidence for their public health campaign.
Activities
Whole-class deconstruction of the three hook sources: teacher models a source evaluation framework (SIFT: Stop, Investigate the source, Find better coverage, Trace claims) by thinking aloud through the peer-reviewed abstract, identifying author credentials, peer-review process, and potential funding bias, then inviting students to apply the same lens to the WHO page and the Instagram post.
Introduce a structured 'Source Evaluation Card' graphic organizer with columns for: source type, author/organization, date, evidence base, potential bias, and credibility rating (1–4). Students individually complete a card for each of the three hook sources to consolidate the modeled framework.
Jigsaw source-comparison activity: small groups each receive a different set of three sources on one of three topics (asthma, sedentary behavior, or blood glucose regulation)—one peer-reviewed article excerpt, one health organization page (e.g., CDC, NHS), and one popular media article. Groups complete Source Evaluation Cards for all three, then discuss which source(s) they would cite in a campaign and why.
Gallery rotation: groups post their completed Source Evaluation Cards on the wall; students do a silent 5-minute walk to read other groups' evaluations, leaving a sticky-note comment ('I agree because…' or 'Consider also…') on at least two other groups' cards, building a shared class resource of evaluated sources.
Whole-class debrief: teacher facilitates a discussion connecting source credibility to the campaign task—'If your campaign makes a claim that turns out to be from an unreliable source, what are the consequences for your audience?' Students record a personal reflection in their science journal: which source type they found hardest to evaluate and one strategy they will use when researching their own campaign topic.
Campaign research launch: students identify their chosen campaign topic (from L11) and use the Source Evaluation Card to begin locating and vetting at least two credible sources they will use in their public health campaign, bookmarking or recording citations in their science journal.
Teacher Notes: A common misconception is that any website ending in '.org' or '.gov' is automatically trustworthy; explicitly address this by showing that some .org sites represent advocacy groups with commercial or ideological interests. For students who struggle with academic language in peer-reviewed abstracts, provide a simplified annotation guide that highlights key sections (methods, conclusions, funding disclosure) so they can evaluate the source without needing to fully comprehend every technical term.
Prior Knowledge
Students have studied all four major body systems (digestive, circulatory, respiratory, musculoskeletal) and can describe their structures and functions.
Students have completed L11 and can explain how lifestyle factors (diet, exercise, smoking) and diseases (type 2 diabetes, asthma) disrupt body system function and cascade across interconnected systems.
Students have been maintaining a science journal throughout the unit and are familiar with recording observations and reflections.
Students have been introduced to the summative campaign task and have begun thinking about their chosen lifestyle factor or disease topic.
Students have basic familiarity with internet searching but have not yet been formally taught structured source evaluation in this unit.
Duration Minutes: 45
Hook: Display two contrasting headlines side by side: 'Government Bans Sugary Drinks in Schools to Fight Diabetes Epidemic' and 'Personal Choice or Public Health Crisis? Critics Say Soda Bans Go Too Far.' Ask students: Who is responsible for keeping your body systems in balance — you, or society?
Order: 13
Title: Science Meets Society: Ethics, Responsibility, and Public Health Recommendations
Targets
Criterion D – Reflecting on the Impacts of Science (strands i, ii, iii): 'evaluation of how scientific understanding of body systems informs public health recommendations; consideration of ethical and social implications of health interventions; discussion of individual and community responsibility for maintaining systemic balance'
Debatable inquiry question: 'To what extent are individuals responsible for maintaining the balance of their own body systems through lifestyle choices?'
Debatable inquiry question: 'Is it more effective to treat a disease by targeting a single organ or by considering the body as an interconnected system?'
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being.'
Global Context – Identities and Relationships: 'Health, well-being, and lifestyle: how the body's interconnected systems sustain physical health and how personal choices affect systemic balance'
ATL – Thinking (Critical Thinking): 'Draw reasonable conclusions and generalizations from evidence' — applied here to evaluating the strength of arguments for individual versus collective health responsibility
Related concept – Balance: 'What does balance mean at the level of the human body, and how do systems work together to maintain it?' — extended to the social dimension of who maintains that balance
Lesson Id: L13
Objective: Students can evaluate the ethical and social implications of health interventions and discuss the extent to which individuals and communities share responsibility for maintaining body system balance.
Activities
Structured controversy warm-up (5 min): Students do a quick silent write responding to the debatable inquiry question 'To what extent are individuals responsible for maintaining the balance of their own body systems through lifestyle choices?' — recording their initial position on a spectrum from 'entirely individual' to 'entirely collective.' Positions are briefly shared aloud to surface the range of views in the room.
Case study carousel (15 min): Four stations around the room each present a real-world health intervention scenario — (1) a sugar tax on beverages, (2) mandatory physical education in schools, (3) pharmaceutical management of blood glucose in type 2 diabetes, (4) smoking bans in public spaces. At each station, students read a short prompt and respond to two questions on a sticky note: 'What body system balance does this intervention target?' and 'Who bears the most responsibility here — the individual, the community, or science/medicine?' Groups rotate every 3–4 minutes.
Whole-class debrief and ethical framework introduction (8 min): Teacher facilitates a discussion drawing on carousel responses, introducing two simple ethical lenses students will use in their campaign — autonomy (an individual's right to make personal choices) and beneficence (acting in the best interest of the community). Students add these terms to their science journals with a brief definition and one example each from the carousel.
Debate fishbowl (10 min): A small group of 4–5 volunteers sits in the centre and debates the second debatable inquiry question: 'Is it more effective to treat a disease by targeting a single organ or by considering the body as an interconnected system?' The outer circle listens and records at least one claim and one piece of evidence they agree or disagree with. After 8 minutes, the outer circle shares reactions for 2 minutes.
Campaign planning bridge (7 min): Students return to their chosen campaign topic from L12 and complete a structured planning frame in their science journal: (a) Which body systems are disrupted? (b) What ethical tension exists between individual choice and public health? (c) What is ONE evidence-based recommendation your campaign will make, and which audience — individual or community — is it directed at? This frame feeds directly into L14 campaign production.
Teacher Notes: A common misconception is that health is purely a matter of personal willpower; scaffold students toward recognizing structural and social determinants of health without dismissing individual agency entirely — framing it as a spectrum rather than a binary helps. For students who struggle with abstract ethical reasoning, anchor every discussion point back to a concrete body system example (e.g., 'If someone cannot afford fresh food, how does that affect blood glucose regulation and the digestive-circulatory interaction?') to keep the science central.
Prior Knowledge
Students can explain how lifestyle factors such as diet, exercise, and smoking, and diseases such as type 2 diabetes and asthma, disrupt body system function and cascade across interconnected systems (L11).
Students can evaluate the credibility and potential bias of peer-reviewed, health organization, and popular media sources, and have already selected evidence for their campaign topic (L12).
Students can explain how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate and interact, and can define homeostasis and describe how the body maintains stable internal conditions (L6, L7).
Students have drawn evidence-based conclusions from their physical activity investigation and evaluated the reliability of scientific methods (L10).
Duration Minutes: 45
Hook: Display three real-world public health campaigns side by side (e.g., an anti-smoking poster, a diabetes awareness infographic, and a physical activity video thumbnail) and ask: 'What makes one of these more convincing than the others — and what would a scientist say is missing from the weakest one?' Students share quick observations before pivoting to their own campaign work.

Title: Designing and Producing the Public Health Awareness Campaign
Targets
Criterion A – Knowing and Understanding (strands i, ii, iii): 'accurate recall and explanation of body system structures, functions, and interactions; correct use of scientific terminology; application of knowledge to explain how lifestyle or disease disrupts systemic balance'
Criterion D – Reflecting on the Impacts of Science (strands i, ii, iii): 'evaluation of how scientific understanding of body systems informs public health recommendations; consideration of ethical and social implications of health interventions; discussion of individual and community responsibility for maintaining systemic balance'
Statement of Inquiry: 'Understanding how body systems perform specialized functions and interact to maintain balance empowers individuals to make informed choices that support their own health and well-being.'
Debatable inquiry question: 'To what extent are individuals responsible for maintaining the balance of their own body systems through lifestyle choices?'
Debatable inquiry question: 'Is it more effective to treat a disease by targeting a single organ or by considering the body as an interconnected system?'
Related concepts – Function, Interaction, Balance: illustrated through the campaign's explanation of how disruption in one system cascades across others
ATL – Communication Skills: 'Use a variety of media to communicate scientific understanding to different audiences'
ATL – Information Literacy: 'Access information to be informed and inform others; evaluate the credibility of sources'
ATL – Organization Skills: 'Keep and use a record of learning (science notebook / lab journal)' — used in the pre-production checklist and self-assessment steps
Global Context – Identities and Relationships: 'Health, well-being, and lifestyle: how the body's interconnected systems sustain physical health and how personal choices affect systemic balance'
Lesson Id: L14
Objective: Students can synthesize their biological knowledge, evaluated sources, and ethical reasoning to create a media campaign that accurately communicates how a chosen lifestyle factor or disease disrupts systemic balance and offers evidence-based recommendations to a target audience.
Activities
Campaign blueprint review (5 min): Students open their science journals and complete a pre-production checklist — confirming their chosen lifestyle factor or disease, their target audience, at least two evaluated credible sources, and the specific body systems they will address — before beginning any production work.
Structured drafting workshop (15 min): Students work independently or in pairs to draft or refine the core content of their campaign (poster, digital infographic, or short video storyboard), using a provided scaffold that prompts them to: (1) name and explain the disrupted system(s) using accurate terminology, (2) describe how the disruption cascades across interconnected systems, (3) state homeostatic consequences, and (4) offer at least two evidence-based recommendations linked to a cited source.
Peer critique protocol (10 min): Students exchange drafts with a partner who chose a different topic and use a structured feedback frame — 'I notice… / I wonder… / One scientific term to add or correct is…' — to give targeted feedback on scientific accuracy, clarity for a non-specialist audience, and source citation.
Revision and production (10 min): Students act on peer feedback, revising scientific language, strengthening system-interaction explanations, and finalizing the visual or multimedia elements of their campaign product.
Gallery walk and self-assessment (5 min): Completed or near-final campaigns are posted or projected around the room; students do a brief silent gallery walk, then complete a one-minute self-assessment against the Criterion A and Criterion D descriptors — identifying one strength and one area still to polish before final submission.
Teacher Notes: A common weakness at this stage is that students explain a single organ's dysfunction (e.g., 'the pancreas stops making insulin') without tracing the cascade across multiple systems — prompt them explicitly with 'Which other system is affected next, and how?' to push toward the Interaction and Balance concepts. For students who struggle with media production tools, prioritize scientific accuracy over polish: a hand-annotated diagram with precise terminology scores higher on Criterion A than a slick infographic with vague claims.
Prior Knowledge
Students have defined the four major body systems and can accurately describe their structures and functions (L1–L5).
Students can explain how the circulatory, respiratory, digestive, and musculoskeletal systems interact during physical activity (L6).
Students can define homeostasis and explain blood glucose regulation and body temperature control as examples of systemic balance (L7).
Students have collected, processed, and evaluated experimental data from their physical activity investigation and drawn evidence-based conclusions about system interactions (L9–L10).
Students can explain how lifestyle factors (diet, exercise, smoking) and diseases (type 2 diabetes, asthma) disrupt body system function and cascade across interconnected systems (L11).
Students have evaluated the credibility and potential bias of peer-reviewed, health organization, and popular media sources and have selected reliable evidence for their campaign (L12).
Students have examined the ethical and social implications of health interventions and discussed individual versus community responsibility for maintaining systemic balance (L13).

Stage4 Data
Briefs
Brief: At the end of L2, students complete a three-prompt exit ticket: (1) label two organs on a simple digestive system outline and state one function for each, (2) distinguish between mechanical and chemical digestion in one sentence each, and (3) explain where nutrient absorption occurs and why. Responses reveal whether students can accurately recall organ structures and functions and use foundational scientific terminology before the unit builds toward system interactions.

Slot Label: Inquiry Design Formative Check
Recommended Tool Type: formative
Brief: After completing their physical activity investigation across L8–L10, students submit a structured lab report in which they present their processed data (tables and graphs), interpret results to explain how exercise affects heart rate and breathing rate, and critically evaluate the reliability and limitations of their method—revealing the depth of their scientific inquiry and data reasoning skills.
Timing: after
Targets
Criterion B – Inquiring and Designing (strands i, ii, iii): identify a focused problem, formulate a testable hypothesis linking two body systems, and plan a method with appropriate variables and controls
Criterion C – Processing and Evaluating (strands i, ii, iii, iv): collect, record, and process data from their body-systems investigation, interpret results in terms of system interaction and balance, evaluate the reliability of their method, and suggest improvements, directly connecting experimental evidence to conceptual understanding
Factual inquiry question: 'What measurable indicators (e.g., heart rate, breathing rate) reflect the current state of body system balance?'
Conceptual inquiry question: 'In what ways do body systems interact so that a change in one system affects the others?'
ATL – Thinking (Critical Thinking): Draw reasonable conclusions and generalizations from evidence — after collecting heart rate and breathing rate data during their physical activity investigation, students analyze graphs and tables to draw conclusions about how the circulatory and respiratory systems interact under stress, justifying their claims with specific data points
ATL – Self-Management (Organization Skills): Keep and use a record of learning (science notebook / lab journal) — students maintain a structured science journal throughout the unit, recording observations, hypothesis revisions, data tables, and reflections after each inquiry activity
Scientific inquiry skills: designing a fair test, measuring physiological variables, processing and evaluating experimental data
Interactions between systems: how the circulatory, respiratory, digestive, and musculoskeletal systems cooperate during physical activity
Brief: Students respond to three to four carefully constructed misconception statements about how lifestyle factors and diseases affect body systems (e.g., 'Asthma only affects the lungs, so it has no impact on the circulatory system'), marking each as agree, disagree, or unsure and writing a one-to-two sentence justification that corrects or confirms the claim using scientific reasoning. Their written justifications reveal whether students understand cascade effects across interconnected systems or still hold isolated, single-system thinking.
