A series circuit is an electric circuit with one complete loop from one end of a battery to the other end.

A circuit diagram is a simple and clear way of showing the setup and components in an electrical circuit.

Circuit symbols are used to show electrical components in a circuit. They are simple to draw and easy to recognise.

A complete circuit is one with no gaps, so electricity is able to flow round the circuit.

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. 

This unit covers electric current, potential difference, and resistance in series and parallel circuits. It also explores charge separation, electron transfer, and electric fields. The unit focuses on interpreting data, identifying patterns, and drawing conclusions using scientific knowledge.
