Water Cycle

I love when our curriculum gives us a science-based unit. My kids LOVE science experiments! We did two today:
1. A "cloud" of shaving cream over a cup of water - making it "rain" by pouring food coloring onto the cloud. When a cloud gets too heavy with its contents, it rains! (We made too big of a cloud, and ran out of blue food coloring to compensate, so we added some red into the mix and eventually got a great rainstorm!)

2. As water in the air rises --> evaporation, it cools --> condensation, and falls --> precipitation. We put warm water in a glass jar and placed ice cubes on the cover. As the steam rose, it cooled and formed water droplets. This one was a little difficult to see as the condensation also formed on the walls of the glass - so we lifted the lid to see the rain!

We've been reading the following books to learn about the water cycle:
