I teach Newton’s Laws of motion using a hovercraft. A few weeks ago I had the opportunity to teach a large group of elementary age children. One of the parents snapped these photos and I am so glad to have them. It was just a fun day. 
Daniel was my helper.
We had a father and a grandfather there and I was so glad that they were willing to help. Timothy, Mark, and Daniel all took rides, but I don’t have photos of all of them.
I think this picture is hilarious. My favorite part of the class was after the kids left and all of the adults took a turn on the hovercraft.
