Choosing and using conductors and insulators (non-statutory)
I can explain the difference between electrical conductors and insulators and can identify where each type of material should be used.
Choosing and using conductors and insulators (non-statutory)
I can explain the difference between electrical conductors and insulators and can identify where each type of material should be used.
Lesson details
Key learning points
- An electrical conductor is a material that allows electricity to pass through it easily.
- An electrical insulator is a material that does not allow electricity to pass through it easily.
- Electrical insulators help keep us safe from the dangerous effects of electricity flowing through conductors.
- Scientists and engineers choose different materials that are electrical conductors and insulators to solve problems.
Common misconception
Only metals are electrical conductors. All non-metals are electrical insulators.
Children will be taught some non-metals are poor insulators, e.g. water as it can contain dissolved minerals which are electrical conductors.
Keywords

Electrical conductor - An electrical conductor is a material that allows electricity to pass through it easily.
Electrical insulator - An electrical insulator is a material that does not allow electricity to pass through it easily.
Appliance - An appliance is a device or piece of equipment designed to perform a specific task.
Equipment
Equipment to make a buzz-wire game: buzzers, cells, stiff wire, flexible wire, tape, stiff board or polystyrene to act as a stand and other materials which are insulators and conductors.
