Me and my class did a water cycle experiment and this is what we had to do. We put water in a zip lock bag and drew on it with a sharpie. Then we filled up a bit of the bag with water and put some dye in to turn the water blue. We put it next to a sunny window. Next the heat of the sun made the water evaporate and turn into a gas. Then the water built up at the top of the the zip lock bag then the water got to heavy. It started to rain (drip down the side) then it went back to the bottom of the bag.
