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.
