Making simple switches
- 60 or more mins
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 operate as an input device that make a gap in the circuit to stop electricity flowing when they are open. A circuit will normally also have at least one output device, such as a buzzer to produce sound or a bulb to produce light.
In this activity, pupils assemble a doorbell circuit. This develops understanding of how switches are used and how electric circuits function. This could be used at Key Stage 2 as a design and make project.
The activity sheet includes teachers' notes, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved nations; England, Northern Ireland, Scotland and Wales.
All activity sheets and supporting resources are free to download, and all the documents are fully editable, so you can tailor them to your students' and your schools' needs.
