Texas Essential Knowledge and Skills for Science

Teacher's field guide

What Students Need to Do: Students make drawings, diagrams, or simple 3D objects to show how something looks, works, or changes. They use their work to explain an idea, or build and test a simple solution to a stated problem.
What Mastery Looks Like: A student chooses materials and details that fit the purpose. The student can explain what each part represents and improve a design after testing it.
Common Misconceptions: Students may think a model must be full size or look exactly like the real object. They may add decorations without showing key parts or steps. They may also treat the first design as finished instead of testing and changing it.
How to Assess It: Exit ticket: Draw and label what happens to an ice cube left in the sun. Add one sentence explaining the change.

Lesson moves

Give pairs clay, straws, and paper to build a model showing how a seed changes as it sprouts.
Ask students to draw a rain puddle before and after sunshine, then write one sentence explaining the change.
Play Model Match: students pair picture cards of real objects with diagrams or models and explain each match.
Challenge students to build and test a foil roof that keeps a toy animal dry under a spray bottle.
