    I love all these fun kids science project ideas. That is what I want my kids to think about science- that is fun, exploration, to satisfy our curiosity. How they are introduced to science totally matters.

    The experiment How Clouds Make Rain was a game changer for my classroom. When I used it this year, I could see that light of understanding turn on in their eyes. After we did this experiment, they would have discussions among themselves of why it was raining, and what happens if it started raining harder. Thank you for this great idea to help them understand their world around them!
