An electrical circuit is a closed loop or path that electricity can flow through to make a component work.

A component is a device in a circuit that has a specific function.

A circuit symbol is a simple picture or shape used to represent a component in a circuit diagram.

A circuit diagram is a pictorial representation of a circuit.

Circuit symbols and diagrams

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

This unit explores how circuit components like lamps and buzzers function, including the effect of cell number and voltage. It covers using symbols in circuit diagrams, planning scientific enquiries, taking precise measurements, recording data, and presenting findings with evidence and conclusions.
