A few days ago Rooms 7&8 were with Mr.Hendricks to observe a little challenge. His challenge was to lift someone up with his thumb. He came out with a weight and a block of wood. We carefully watched as he turned both objects into a seesaw. Later on Joshua stepped on it then Mr.Hendricks pushed the wood down with his thumb. What was really doing the magic was the fulcrum. The fulcrum gives the wood ease to come down. That day we learnt that simple machines can do a ton of work.
