Where does a puddle go?
Learning objective: Explain evaporation as liquid water changing into water vapour, using an everyday observation.
- Notice & wonder · 5 minCompare pictures of a puddle in the morning and afternoon. Ask learners what changed and where the water might have gone.
- Build an explanation · 10 minUse a simple drawing to model liquid water changing into water vapour. Discuss how evaporation differs from boiling.
- Plan a fair test · 15 minUse equal amounts of water in identical dishes. Plan to compare different airflow conditions and predict which will lose water faster.
- Check understanding · 5 minExit ticket: explain where the puddle’s water went, and name one observation that could support your explanation.
