How we move things.

Two kinds of force...

The kind of force that Grover and his friends used. 

The kind of force when you use when you go down a slide.  

The kind of force that wind uses.  Hint:  It was in the story. 

When we did the pendulum painting, we investigated this object's motion.  

We investigated this object's motion in our "Ball and Bat Investigation".

We used this to push the ball in our class investigation.

This made our boats move in our boat design project. 

This made the marbles go in a different direction.

On the Magic School Bus, Ms. Frizzle and the class discovered that you needed this to play baseball or even to walk.
