SCGS ScienceYear 9 PhysicsName______________________Electricity 1This activity uses PhET simulation– Circuit Construction Kit: DC - Virtual Lab.This is a guided inquiry task. You must read and follow the instructions carefully.1Circuit SymbolsDrag some components out onto the work area from the component tool bar onthe left. Use the button on the bottom right to toggle between the drawings andthe circuit symbols.Completethe table below. Make sure you use a rulercomponentsymbolcomponentsymbolwireresistorbattery / cellswitchlight bulb *fuse*we use a different symbol for lamp or light bulb in Australia.2Circuit diagramsDiagrams show engineers and scientist how to connect circuits. They are notpictures. There can be more than one correct diagram. They have strict rules.1.Always drawn with pencil and ruler.2.Components are represented using circuit symbols3.Components are not placed on corners4.Wires are horizontal or vertical linesUse the circuit diagram on the right tobuildthe circuit on the work area. Close theswitch and the bulb should light up.CHECKPOINT #13Electric CurrentWhilst the switch is closed and the bulb is lit you should notice the blue circlesmoving around. These represent thechargesmoving around the circuit. In metalwires the charges are theelectrons. Open the switch and the electrons stopmoving.
