Fighting Gravity

Hoiho class watched as Josh jumped off a school chair. He said it was easy. When he tried  jumping back on the chair from the ground he said it was harder because he was fighting  gravity. 

The  Moon is going around the earth because of the gravity coming from the earth pulling the moon towards the centre of the earth. To show you some girls and some boys showed what it looks like  by making the moon and the earth. 

There is less gravity on the moon than on earth because the moon has less mass. We got eight people to be the earth and then four people to be the moon. 

We put the pin on the ground then we put a piece of wood on top of the pin. The pin held the piece of wood up. 

Kimberly stood on the piece of wood. Her weight made the pin go into the wood.
