Pupils investigate whether the length of wires in a simple circuit effects the brightness of a bulb.
PoS - compare and give reasons for variations in how components function, including the brightness of bulbs, the loudness of buzzers and the on/off position of switches; use recognised symbols when representing a simple circuit in a diagram
NaG - building on their work in year 4, pupils should construct simple series circuits, to help them to answer questions about what happens when they try different components
WS - systematically identifying the effect of changing one component at a time in a circuit
