Year 4 have been making houses with security lights in DT. First we had to design and make a house out of a cardboard box. Next we had to have a doormat which had foil on the underside. We constructed an electrical circuit using a battery, a bulb in a holder and three wires. The end of the wires poked out underneath the doormat. When pressure was put on the doormat the circuit would be connected and the security light would light up.
