Mr. Z was here for science week. 3rd and 4th class did experiments on forces, gravity and built go-carts. We learned that the more friction, the slower it goes. He told us what gravity does and that we wouldn't go far without it. For the go-carts we used axles, straws and wheels. They went fast when there wasn't much friction. Then we built a race track to race our go-carts. We really enjoyed having Mr.Z in our school and especially enjoyed science week! by Ava, Dylan and Charlie.S
