This activity is about simple working electrical circuits, different switches and where they are used in everyday life. The students work in pairs, making a pressure switch and then wiring it in to a circuit containing a pre-made motorised buggy and a battery. Once the switch is activated the buggy moves. The students then work with kits which contain instructions and different switches, i.e. reed, vibration, tilt etc. in them and they make up different Burglar Alarms. A word of warning: This activity is very noisy!
