Describing, measuring and classifying matter, and how its properties and changes can be observed and explained.
2.6 Matter and its properties: the physical properties of matter determine how it is described, sorted, and used

2.10C Investigate types of severe weather, for example a flood, tornado, or hurricane, and explain that certain events happen more often than others in a particular region
2.11 Earth and space: products made from earth materials, and the materials themselves, matter in daily life
2.11A Tell natural resources apart from manmade resources
2.11B Describe how people can lessen their impact by choosing to save and properly dispose of materials, for example using less, recycling, or reusing metal, plastic, and paper
Organisms and Environments
How living things meet their needs, interact with each other and their surroundings, and change over time.
2.12 Organisms and environments: living things have basic needs that are met through interactions with their surroundings
2.12A Describe how the physical features of environments, including how much rain falls, support the plants and animals of an ecosystem
2.12B Create and describe food chains that name producers and consumers, showing how animals rely on other living things
2.12C Demonstrate and explain the ways certain plants need water, wind, or other living things to pollinate and to scatter their seeds
2.13 Organisms and environments: organisms have structures and processes that help them interact with and survive in their surroundings
2.13A Identify plant seeds, fruits, flowers, leaves, stems, and roots, and compare how each structure helps various plants stay alive by meeting basic needs
2.13B Record and compare how animal structures and behaviors help animals locate food, water, and air and bring them in
2.13C Record and compare how belonging to a group helps animals get food, protect themselves, and cope with change
2.13D Investigate and describe some distinctive animal life cycles in which the young do not look like their parents, including frogs and butterflies
Recurring Themes and Concepts
Big ideas, like patterns, cause and effect, systems and models, that connect every area of science.
2.5 Recurring themes and concepts: apply big ideas that cut across science to connect learning across subject areas
2.5A Recognize patterns and apply them when describing phenomena or designing solutions
2.5B Predict and investigate relationships of cause and effect in science
2.5C Measure objects and describe their properties by size and by quantity
2.5D Examine a whole's parts to define a system or build a model of one
2.5E Identify matter's properties and the forms energy takes
2.5F Describe how the structure of objects, organisms, and systems relates to what they do
2.5G 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.
2.1 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
2.1A Pose questions and frame problems that come from observing, reading, studying phenomena, or working with models and investigations
2.1B Plan and carry out simple descriptive investigations using scientific practices, and design solutions to problems through engineering practices
2.1C Name, explain, and model safe behavior in classroom and field investigations, following the safety standards approved by the Texas Education Agency
2.1D Observe, measure, test, and compare using goggles, heat-resistant gloves, and hand lenses; trays, bowls, cups, and beakers; notebooks; stream tables; gravel, sand, and soil; flowering plants; student and demonstration thermometers and rain gauge; flashlights; ramps, balls, and spinning tops; drums and tuning forks; sandpaper, wax paper, and aluminum foil; flexible and non-flexible items; hot plate; magnets; Sun-Moon-Earth model; and life cycle models of frogs and butterflies
2.1E Gather observations and measurements to serve as evidence
2.1F Record and organize data using simple graphs, symbols, words, numbers, and pictures
2.1G Build and apply models that stand for phenomena, objects, and processes, or create a prototype that solves a problem
2.2 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
2.2A Recognize basic strengths and weaknesses of models, such as how their size, properties, and materials affect them
2.2B Analyze data by spotting important features and patterns
2.2C Apply math ideas to compare two objects that share a common attribute

2.3B Share explanations and solutions alone and with others, in many settings and formats
2.3C Listen closely to the explanations of others to pick out key evidence, and take part respectfully in scientific discussion
2.4 Scientific and engineering practices: learn about the work of scientists and why scientific research and innovation matter to society
2.4A Explain how others can be helped by science or by an innovation
2.4B Name scientists and engineers, for example Jane Goodall, Mario Molina, Marie Daly, and Alexander Graham Bell, and explore the different jobs that scientists and engineers do
How many 2nd Grade TEKS Science Standards are there?
There are 45 2nd 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 2nd 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 2.6A mean?
TEKS science codes read grade, knowledge and skills statement, student expectation. In 2.6A, 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.
