- Year 4
Building simple circuits
I can build a simple series electrical circuit.
Lesson details
Key learning points
- A complete electrical circuit is made when all components are connected together correctly.
- Wires must be connected to the positive and negative end of the battery in a complete loop.
- A series circuit is when all the components are in the same loop.
- Scientists try out different ideas in order to solve problems.
Keywords
Circuit - An electrical circuit is a closed loop or path that electricity can flow through to make a component work.
Components - Components are the parts of a circuit.
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.
Series - A series circuit is when all the components are in the same loop.
Common misconception
Misconceptions associated with incomplete circuits: one wire to battery; connections to the same end of the battery; wires the wrong way around; not connecting clips to metal.
Children will be taught about the number of wires needed and how to connect to the battery. They will also be given the chance to explore circuit building themselves.
Equipment
Components for simple electric circuits: cells, wires, bulbs in holders, buzzers and motors.
