In design on Friday we worked on our Rube Goldberg machines. In our machines we had to have the number of elements and simple machines equal to the number of people in the group. Our group was almost done building but unfortunately we didn’t have enough simple machines so we had to completely restart. We all went back to our table and thought up a whole new design, this time with enough simple machines. Our design now has a pulley, inclined plane, fulcrum and a lever. The fulcrum and lever make up a see saw and the inclined plane makes a ramp. So far we have built the first element, a ramp leading to a see saw. Next session we will try to get the see saw to work and build the next element, which is a track leading to a pencil that releases a wind up car.
