Today we continued our science lesson on forces, by playing with our Hoppers we made yesterday. The students cut and folded a piece of paper. Then they added a rubber band. They then worked with a partner to launch their hopper. Some of the hoppers flew high into the air. We discussed that when we were stretching out the sides of the hopper we were PULLING on the hopper. When we released the hopper from the ruler the rubber band PULLED the sides back together and the hopper PUSHED itself off the table into the air. This was a fun interactive activity to see how push and pull work together to create movement.
