Choose the Right Material

What students learn

Students learn that some materials let electricity move and others block it. Begin with so students hear the difference right away.

Why it matters

Circuit parts are not all made from the same material. Use to connect the idea to familiar objects from home or school.

Learn the idea

Conductors let electric current pass. Insulators block current and help keep people safe. Watch to see why some materials belong on wires, tools, and covers.

Try it

Sort items like a spoon, foil, plastic, rubber, and a paper clip into conductor or insulator groups. Then ask the student to explain why the material helps or slows electricity.

Parent guide

If the child only says "metal," ask which side of the sort it belongs on and why. That extra question pushes them from guessing to explaining.
