Forces!
In science we've started learning about forces. Did you know you use forces such as pushes and pulls to move things every day? Today we did an experiment called "puffing power." We blew through a straw to move a ball. We found that the harder we blew the faster the ball moved and and the softer we blew the slower the ball moved. We also had some races with friends.

We think it is so neat to use force through a straw! We wonder if light balls are easier that heavy balls to move?
