Why does water evaporate?
Have you talked about your ideas?
Do you agree with one of the characters or do you think something different?
Here are some ways of finding out more:
1) Pour some water into a saucer. Observe what happens if you
leave it for two or three days. Does the water level change? If so, why?
2) Compare what happens if you leave the saucer in a cool area and if you leave it in a warm area. Measure the rate of evaporation in both areas.
3) How do hand driers work if the temperature is less than 100°C?
