Conductors and insulators
Recognise some common conductors and insulators, and associate metals with being good conductors of electricity
Lesson
Set out your lesson
“Conductors and insulators means sorting materials that let electricity through (conductors, often metals) from those that do not (insulators). We will practise once together, then check a fresh example.”
Bring to the table
- Safe samples or photos: metal spoon, plastic spoon, rubber band, wooden stick
- Two labels: Conductor / Insulator
Extra for the adult
Worked example. A metal key is a conductor. Plastic coating on a wire is an insulator.
Optional challenge. For Conductors and insulators, explain why plugs use plastic housings around metal pins.
What to notice. Keep one parent note: sorts; metal=conductor; support used. This session samples material roles, not mastery of every electrical test.

Conductors and insulators means sorting materials that let electricity through (conductors, often metals) from those that do not (insulators). We will practise once together, then check a fresh example.
Spend about 12 minutes sorting household materials into conductor vs insulator, then checking a fresh object.

Check understanding
- Define conductors (allow electricity to flow through) and insulators (block electricity)
- Test at least six materials and correctly classify them as conductors or insulators
- State that metals are generally good conductors and explain why wires are made of metal with plastic coating
“Can your child test objects in a circuit and explain why metal objects let electricity through but rubber and plastic don't?”
