A battery is a component that uses a chemical reaction to make electric charge flow round a circuit.

Things can have an electrical charge that is positive or negative. If there is no charge, they are neutral.

Electrons are the charges in conductors that flow to give an electric current.

Electric current is the flow of electric charge in a circuit.

Electric current

Science

In the Magnets and electromagnets unit, they will build on this knowledge to learn about how electric current flows through electromagnets, factors that affect the strength of electromagnets and uses of electromagnets that include a simple electric motor.

In Changing circuits unit (Y6), pupils learnt to construct simple circuits, and about complete circuits, circuit diagrams and how the number and voltage of cells in a battery affect components in a circuit. 

Series circuits

Physical activity and equipment requiring safe use

A battery has one positive terminal and one negative terminal.

A battery has a neutral terminal and either a positive or a negative terminal.
