Electricity is needed for lighting, heating and making machines and appliances work.

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.

An appliance is a device or piece of equipment designed to perform a specific task.

Choosing and using conductors and insulators (non-statutory)

Science

In the Changing circuits unit, pupils learnt to give reasons for variations in how components function, such as the brightness of bulbs. In the Series circuits unit, they will build on this knowledge to find rules for electric current and voltage in series circuits 

In the Simple electrical circuits units, pupils learnt to construct a simple series electrical circuit, identifying and naming its basic parts. In this Changing circuits unit, pupils will build on this knowledge to compare and give reasons for variations in how components in a circuit function
