Outcomes
- Pupils understand that light travels at different speeds in different media.
- Pupils understand that the changing speed of light leads to the pheonmenon of refraction.
Specification References

Starter
- Ask pupils to estimate their top speeds on land and in water.
- Land: 10m/s (100m runner); water: 2.4m/s (50m swimmer)
