Water Cycle in a Bag
Ask your teacher to help you with this. Pour a little bit of water (with blue food colouring, if you have it) into a clear, sealable plastic bag. Seal it and tape it to a sunny window. Watch what happens over the next few hours. You should see the water 'evaporate' (turn to vapour), 'condense' (form droplets on the bag), and 'precipitate' (run back down like rain).
