The Water Cycle Bag

We have been studying the water cycle and have had this ziplock bag hanging in our window watching what happens as heat is added or taken away. Condensation is formed inside the bag and runs down the sides (precipitation) and then accumulates with the water in the bottom of the bag. We have also noticed a drop in the water in the bag, which means evaporation is taken place as well. It is awesome to watch the stages of the water cycle come to life!
