We started with the excitement of burning about 25 model tudor houses, made from cardboard boxes as part of a history topic, in a re-enactment of the great fire of Londonin the school field.

The children then made a big ‘electrical’ circuit by holding hands in a class circle and lighting a cosmic ball, demonstrating complete circuits and the effect of a switch. This was followed by each child making simple electrical circuits with bulbs, different numbers of batteries in series and small motors. We then set up a working seascape and lighthouse model and talked about how lighthouses work. Finally the children learnt about what gives out light and what simply reflects it (like the moon) and the workshop finished with a question and answer session which ranged from discussion of power to whether our sun would turn into a wormhole.
