Water Cycle Experiment Worksheet

Science experiments lesson 9: Water cycle in a bowl · Set 837 · 40 questions

What you do (Up as vapour, down as drops): 1. Pour some water into the big bowl and stand the small cup in the middle. 2. Cover the bowl tightly with cling film. 3. Put a few ice cubes on top of the film, over the cup. 4. Leave it in the sun for an hour and look for drops in the cup.
