You need: a big bowl with some water, a small empty cup in the middle, cling film, ice cubes and sunlight. What happens: drops form under the cling film and drip into the cup. Why: the Sun warms the water and some evaporates into water vapour (water as a gas). The vapour touches the cold cover, cools and condenses back into drops, which fall like rain. The same thing makes drops on the outside of a cold glass.
✓ You passed this lesson’s test.
Up as vapour, down as drops — “evaporation and condensation make the water cycle”
Use it for: Class 3–7 lessons on the water cycle, evaporation and condensation; a simple experiment with explanation.
Check: A misty bathroom mirror is condensation too ✓
