Communication

To make sure that this was a group project and not just one person making a catapult we had to communicate our ideas on how to make the catapult. The first idea that we had was to make kind of an H, two long supports on the outsides, and the spoon connected to a popsicle stick on the middle. We couldn’t find a good way for the spoon to want to go up though. So we created the new design in the second photo. Though at first it didn’t have the front support beam. Later we added the back beam because one of us communicated to the rest of the group that the catapult was not stable. The back support also has the added effect of increasing the angle to the ground, which would make the ball have more horizontal force, and not vertical force, which our catapult had lots of when we first constructed. We all agreed that this last idea was a good idea. In summary, we had to communicate for our project to function properly.
