We read our first book about simple machines, Move It! Work It!: A Song About Simple Machines by Laura Salas.
On Monday we will ask Jan if she can help us learn the song in the back of the book.
We also watched a DVD about Levers. It explained the relationship between the fulcrum, load, and effort, in making a lever work.
The morning story mentioned that a baseball bat was a type of lever. After the DVD, I reminded the children about this and they started brainstorming other sports that use levers. They came up with quite a list of levers: golf club, hockey stick, crochet mallet, cricket bat, and tennis racket.
This is just the beginning of our simple machine explorations.
