Troubleshooting problems with circuits
I can solve problems and improve simple circuits.
Lesson details
Key learning points
- A circuit will not work if it is not part of a complete loop with a battery.
- Buzzers only work if they are connected in the correct direction.
- To solve problems with circuits, scientists test whether they are connected correctly and whether the components work.
- Electricians check if circuits have been built incorrectly and with improper wiring.
- When we use electricity and electrical appliances, we need to follow rules to stay safe.
Common misconception
Misconceptions associated with incomplete circuits: one wire to battery; connections to the same end of the battery; wires the wrong way round; not connecting clips to metal.
Children will be taught how to troubleshoot circuits which are not working to address these misconceptions.
Keywords
Circuit - An electrical circuit is a closed loop or path that electricity can flow through to make something work.
Complete - A complete electrical circuit is made when all components are connected together correctly and there are no breaks in the circuit.
Incomplete - An incomplete electrical circuit is made when the components are not connected together correctly or there are breaks in the circuit.
Connectors - Connectors are the places on components where the wires make contact to join it to the rest of the circuit.
Electrician - An electrician is an expert in electrical circuits and electricity.
Equipment
Components for simple electric circuits: cells, wires, bulbs in holders, buzzers and motors.
