An electric shock occurs when electricity passes into our bodies. It can be very dangerous.

High voltage electricity flows with a stronger push than low voltage electricity.

Personal protective equipment or PPE refers to clothes and equipment used by people to keep them safe.

An electrical insulator is a material that does not allow electricity to pass through it easily.

An electrical conductor is a material that allows electricity to pass through it easily.

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.
