Question 107
Work in pairs. Make a model of a school or a house using cardboard boxes, scissors, glue or adhesive tape, cells, a battery or a power supply, switches, lamps, buzzers, an ammeter, other components, wires and connectors. Use cells, a battery or a power supply as an analogy for the mains supply. Design a circuit to operate lamps and other electrical equipment in the building. Lamps in each room must be switched on and off separately. Include other equipment: for example, a school buzzer, an alarm that sounds when an outside door is opened, a meter showing the current, or an emergency switch that turns off all equipment at once. Include anything else you have equipment to make. Demonstrate how all the equipment works and show one fully labelled circuit diagram for all the equipment.
