Knowledge organizers contain the most fundamental knowledge for the topics you are studying.
1. Electricity Year 6 Key Vocabulary Key Knowledge circuit A path that an electrical current Components of a Circuit and Their Symbols can flow around. symbol A visual picture that stands for lamp/bulb something else. (indicator) wire cell/battery A device that stores chemical energy until it is needed. A cell is a single unit. A battery is a collection of cells. lamp/bulb current The flow of electrons, measured (lighting) in amps. switch motor amps How electric current is measured. (open) voltage The force that makes the electric current move through the wires. M The greater the voltage, the more current will flow. buzzer resistance The difficulty that the electric switch current has when flowing around cell (closed) a circuit. electrons Very small particles that travel around an electrical circuit. battery To look at all the planning resources linked to the Electricity unit, These symbols can be used to create electrical circuit diagrams. click here. visit twinkl.com
2. Electricity Year 6 Key Knowledge What will make a bulb brighter or a Series Circuit buzzer louder? A circuit that has only one route for the current to take. If more bulbs or • More batteries or a higher voltage create more buzzers are added, the power has to be shared and so they will be dimmer or power to flow through the circuit. quieter. If just one part of this series circuit breaks, the circuit is broken and • Shortening the wires means the flow of current stops. the electrons have less resistance to flow through. More comp on sharing les ents s power. A broken c irc with no ele uit What will make a bulb dimmer or a ctrical current. buzzer quieter? • Fewer batteries or a lower voltage give less power to the circuit. • More buzzers or bulbs mean the power is shared by more components. • Lengthening the wires means the electrons have to travel through more resistance. visit twinkl.com
