Circuits

Students should:

Recognise that an electric circuit consisting of an energy source (battery) and other circuit components (wire, bulb, switch) forms an electrical system.

Show an understanding that a current can only flow in a closed circuit.

Identify electrical conductors and insulators.

Students should be able to:

Construct simple circuits from circuit diagrams.

Investigate the effect of some variables on the current in a circuit and communicate findings.

- number of batteries (arranged in series)

- number of bulbs (arranged in series and parallel)
