- Use class discussion to review pupils' knowledge and understanding of electrical circuits,
eg draw a simple pictorial representation of a single cell and a single bulb (without holder) on the board. Ask individual pupils in turn to draw connections to make the bulb light. Discuss/vote on whether each one will work. Also ask if differently drawn circuits are the same. Repeat with more than one cell and bulb, in series. Alternatively, ask pupils to work in groups doing the same exercise using prepared cards.
- Ask pupils to test their predictions about whether the bulbs will light using short lengths of wire. Some pupils may need to be reminded about removing insulation from the wires. Others will need to identify the connection points on both the cell and the bulb. Pupils should record their observations, using conventional symbols. Pupils continue to explore the circuits by including simple switches.
- Ask pupils or groups of pupils to explain their observations to others.

- make and explain predictions about circuits,
eg two connections are needed to light a bulb, there has to be a complete circuit, the battery provides 'something' to the circuit
- support their predictions by demonstration circuits, or circuit diagrams
- explain that the bulb(s) light because electricity travels round the circuit
