Jessica's Catapult Project

Jessica and Roy worked on a project for school. It was building a catapult. Jessica with the help of Roy were able to draw a design for the calapult and build it. Jessica's catapult was a 3rd Class Lever. It is suppose to throw a tennis ball. They designed the catapult so it has three different ways to throw the tennis ball depending on how far you want it to go. They went all out on it! She ended up getting a good grade on it. We had the whole family involved in the excitement of the practice launches. :)
