Science with little ones

We have been reading and studying on the water cycle. It is a bit hard for my kids to understand since we live in a very dry area and there is not much natural water cycle happening. The curriculum that I am using for the twins called for an experiment to demonstrate the water cycle, and it really seemed to help them understand it. First I filled a pan 2/3 full of water and brought it to a boil. I removed it from the heat, set it on a hot pad on the table where everyone could watch, and put a cookie sheet covered with ice cubes on top of the pan. After about a minute we lifted the pan and watched the water vapor rise, meet the cold tray and turn into tiny water droplets on the bottom of the tray. When the drops got big enough they “rained” back into the pan. Monday we released our first monarch for this year. I have one caterpillar that will soon make his chrysalis. I also have a baby caterpillar and two eggs that we found Monday when we released the monarch. It has been fun listening and trying to answer all the questions that this has brought up. I wish I could remember them all so I could list them here.

I love the rain thing. That looked neat.
