How switches work
Recognise that a switch opens and closes a circuit, controlling whether a lamp lights or a buzzer sounds
Suggested ages 8–9
Learning journey
Your child is discovering how electricity works — building simple circuits with batteries and bulbs, understanding how switches control electrical flow, and learning which materials conduct electricity and which don't.
Evidence of understanding
- Explain that a closed switch completes the circuit (current flows) and an open switch breaks it (current stops)
- Demonstrate adding a switch to a circuit and using it to control a bulb or buzzer
- Relate the switch concept to everyday switches in the home
Assessment prompt
Can How switches work explain what happens inside the wall when they flip a light switch — that it completes or breaks the electrical loop?
