Rain in a Bag
Evaporation experiments never get old. Take it a step further with this interactive "rain in a bag" activity. Simply draw a nature scene on a plastic bag, complete with a lake and clouds. Fill the bag up with water to the top of the "lake," and hang it in a sunny window. As the days go by, the water will evaporate in to the cloud and, when they can't hold anymore water, it will rain!
