This activity will take approximately 50-60 minutes. Tools/resources required Projector/Whiteboard Components: 2 x AA batteries in holder Electric motor (e.g. 3V 13100 Rpm DC Motor) 3 lengths of wire, each 100-150 mm long (only a single length is required if a battery holder with attached wires is used) Either: 2 metal split pin fasteners and 1 paper clip per pupil, or one switch per pupil Sticky tape or electrical insulation tape. If needed: wire cutters/strippers (to cut excess wire lengths) (Potential sources for these components include Rapid online and TTS group) Optional: Hole punches (ideally single hole punches) Pre-made models of the circuit, for demonstration Electrical circuits An electrical circuit is a group of components that are connected together, typically using wires. The wires are typically copper metal, which is highly conductive, coated with insulating plastic, to prevent electric shocks. The circuit must be continuous (i.e., have no breaks) to allow electricity to flow through the components and back to its source, such as a battery. Switches make a gap in the circuit to stop electricity flowing when they are open. The components included in an electric circuit could range from motors, light sources and buzzers to programmable integrated circuits. The engineering context Circuits form the basis of all electrical equipment, ranging from lighting in homes to televisions and computers. Suggested learning outcomes By the end of this activity students will be able to construct an electrical switch, they will understand that a complete circuit is required for electricity to flow and they will be able to construct an electrical circuit.
