Describing, measuring and classifying matter, and how its properties and changes can be observed and explained.
1.6 Matter and its properties: objects have physical properties used to describe and sort them

1.10C Compare oceans, lakes, rivers, streams, ponds, and puddles in size, shape, clarity, and color, and whether they hold freshwater or saltwater
1.10D Describe and record observable weather characteristics, including whether it is rainy or icy, calm or windy, clear or cloudy, hot or cold, and explain how weather affects the choices people make each day
1.11 Earth and space: products made from earth materials, and the materials themselves, matter in daily life
1.11A Identify and describe how humans, plants, and animals make use of rocks, soil, and water
1.11B Explain the importance of saving water
1.11C Describe ways to save water, for example shutting off the faucet while brushing teeth, and ways to protect natural water sources, for example by not dumping trash in them
Organisms and Environments
How living things meet their needs, interact with each other and their surroundings, and change over time.
1.12 Organisms and environments: the environment consists of relationships between living things and nonliving parts
1.12A Classify living and nonliving things by checking if they produce young and have basic needs
1.12B Describe and record examples of how living and nonliving components interact and depend on each other in terrariums or aquariums
1.12C Identify and illustrate food chains as a way living organisms depend on one another
1.13 Organisms and environments: organisms look like their parents; they have structures and processes that help them interact with and survive in their surroundings
1.13A Identify the external body structures of various animals and compare how those parts let each kind of animal stay alive, get around, and meet its basic survival needs
1.13B Record observations of, and describe, the basic life cycles of three animals: a fish, a bird, and a mammal
1.13C Compare the ways young animals look like their parents
Recurring Themes and Concepts
Big ideas, like patterns, cause and effect, systems and models, that connect every area of science.
1.5 Recurring themes and concepts: apply big ideas that cut across science to connect learning across subject areas
1.5A Recognize patterns and apply them when describing phenomena or designing solutions
1.5B Predict and investigate relationships of cause and effect in science
1.5C Describe objects by how large or small they are compared with others (scale) and by how much there is of them (relative quantity)
1.5D Examine a whole's parts to define a system or build a model of one
1.5E Identify matter's properties and the forms energy takes
1.5F Describe how the structure of objects, organisms, and systems relates to what they do
1.5G Explain how certain conditions or factors lead objects, organisms, and systems to change or to stay as they are
Scientific and Engineering Practices
The ways students do science at every level: asking questions, investigating safely, using evidence and communicating explanations.
1.1 Scientific and engineering practices: pose questions, define problems, and plan and safely carry out classroom, lab, and field investigations, using suitable tools and models, in order to explain phenomena, answer questions, or design solutions
1.1A Pose questions and frame problems that come from observing, reading, studying phenomena, or working with models and investigations
1.1B Plan and carry out simple descriptive investigations using scientific practices, and design solutions to problems through engineering practices
1.1C Name, explain, and model safe behavior in classroom and field investigations, following the safety standards approved by the Texas Education Agency
1.1D Observe, measure, test, and compare with goggles, heat-resistant gloves, hand lenses, trays, cups, bowls, beakers, tweezers, sieves, sifters, primary balance, non-standard measuring items, notebooks, aquariums, terrariums, stream tables, clay, gravel, loam, rock, and sand samples, seeds, plants, windsock, pinwheel, rain gauge, student and demonstration thermometers, straws, ribbons, flashlights, sandpaper, wax paper, aluminum foil, magnets, magnetic and non-magnetic items, hot plate, a Sun-Moon-Earth model, and life cycle models of plants and animals
1.1E Gather observations and measurements to serve as evidence
1.1F Record and organize data using simple graphs, symbols, words, numbers, and pictures
1.1G Build and apply models that stand for phenomena, objects, and processes, or create a prototype that solves a problem
1.2 Scientific and engineering practices: analyze and interpret data to find meaning, features, patterns, and relationships so that evidence-based arguments can be made or designs evaluated
1.2A Recognize basic strengths and weaknesses of models, such as how their size, properties, and materials affect them
1.2B Analyze data by spotting important features and patterns
1.2C Apply math ideas to compare two objects that share a common attribute
1.2D Judge a design or object against criteria to decide whether it works as intended
1.3 Scientific and engineering practices: build explanations supported by evidence and share findings, conclusions, and proposed solutions
1.3A Build explanations and suggest solutions that are backed by data and models
1.3B Share explanations and solutions alone and with others, in many settings and formats
1.3C Listen closely to the explanations of others to pick out key evidence, and take part respectfully in scientific discussion
1.4 Scientific and engineering practices: learn about the work of scientists and why scientific research and innovation matter to society
1.4A Explain how others can be helped by science or by an innovation
1.4B Name scientists and engineers, for example Ernest Just, Sally Ride, and Katherine Johnson, and explore the different jobs that scientists and engineers do
How many 1st Grade TEKS Science Standards are there?
There are 44 1st Grade TEKS Science Standards on this page, in 6 strands: Matter and Its Properties, Force, Motion, and Energy, Earth and Space, Organisms and Environments, Recurring Themes and Concepts, and Scientific and Engineering Practices.
How do I write an assessment for a 1st Grade TEKS Science standard?
Pick a standard on this page and choose Make a quiz. AssessmentWiz opens the generator with the standard's code and text filled in, so every question targets that standard.
What does a code like 1.6A mean?
TEKS science codes read grade, knowledge and skills statement, student expectation. In 1.6A, the first number is the grade (K for kindergarten), the next number is the knowledge and skills statement, and the letter is the student expectation under it.
