Science is everywhere! It can even be found in fingerplays you sing with your child.
The Itsy Bitsy Spider, for example, is a very simple water cycle song. Through the song, children can learn that rain makes things wet and the sun can make wet things dry. They can also learn that too much water at one time can create a reaction like washing a spider from a gutter or rain spout.
