Transcript of Conductors and Insulators

I can name materials that are good at electrical conduction and insulation.
What is an electrical conductor?
An electrical conductor is a material that allows electricity to pass through.
What is an electrical insulator?
An electrical insulator is a material that STOPS electricity from getting through.

Should I make a crocodile clip out of margarine?

Is the filament of a bulb made of metal?

Why is plastic used on the outside of wires?
