identify forms of energy and properties of matter

Texas Essential Knowledge and Skills for Science

Teacher's field guide

What Students Need to Do: Students name energy they can observe, such as light, heat, sound, and motion. They describe and sort materials by properties such as color, texture, shape, flexibility, and state.
What Mastery Looks Like: A student can observe an object or event and identify the energy present using evidence. The student can describe matter with several observable properties and explain a sorting choice.
Common Misconceptions: Students may call matter energy, or think energy is a material that can be held. They may name an object instead of its properties or sort only by color.
How to Assess It: Show a ringing metal bell and an ice cube. Ask students to name one form of energy from the bell and three properties of the ice cube.

Lesson moves

Set up stations with a flashlight, bell, rolling ball, fabric, foil, and clay for students to observe and record energy or material properties.
Ask students to write: How are a glowing lamp and a ringing phone different, and what evidence supports your answer?
Play Property and Energy Sort using picture cards labeled light, sound, heat, motion, rough, smooth, flexible, rigid, solid, and liquid.
Examine classroom tools, then discuss why a metal spoon, rubber eraser, and clear ruler have properties suited to their jobs.
