A switch is part of an electrical circuit than can stop or allow electricity to flow.

Control variables are variables that are kept the same throughout an investigation.

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

A complete electrical circuit is made when all components are connected together correctly and there are no breaks in the circuit.

An incomplete electrical circuit is made when the components are not connected together correctly or there are breaks in the circuit.

Working with electricity

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

In the Everyday materials unit, pupils learnt to identify and name a variety of everyday materials, including wood, plastic, glass and metal. In this Simple electrical circuits unit, pupils will build on this knowledge to recognise some common conductors and insulators, and associate metals with being good conductors

This unit covers constructing simple series electrical circuits, identifying parts like cells, wires, and switches, and recognising conductors and insulators. It also explores how circuits work with lamps and switches. The emphasis is on practical enquiries, making observations, and presenting data.
