Y4 Introducing a Switch

Learning Objectives:

• PoS - recognise that a switch opens and closes a circuit and associate this with whether or not a lamp lights in a simple series circuit; identify whether or not a lamp will light in a simple series circuit, based on whether or not the lamp is part of a complete loop with a battery; construct a simple series electrical circuit, identifying and naming its basic parts, including cells, wires, bulbs, switches and buzzers
• NaG - pupils should construct simple series circuits, trying different components, for example, bulbs, buzzers and motors, and including switches, and use their circuits to create simple devices
• WS - pupils should observe patterns, e.g. that bulbs get brighter if more cells are added, that metals tend to be conductors of electricity, and that some materials can and some cannot be used to connect across a gap in a circuit
