Execute: In our project, our goal was to make an “engine” using the varied materials you see to the above in the comparison chart. In our group, we decided to use plastic spoons and fur we found, it had the best charge. To test out our “engines” we used a pith and tape to see which “engine” had the most powerful charge to do 10 laps of a ruler balanced on a watch glass without touching it. During it is very important to collaborate with one another to decide what our roles and responsibilities were. Annabell and Mikaila were the racers, I was the timer and Maria was the reporter.

Finally, we raced to see which “engine” would have the fastest time. Unfortunately, we did not win, however the other group that did used the same materials as us. Maybe we rubbed ours for too long or something else. If I did this another time I think I would rub the materials together for less time, or try another material. As a team, I think we worked great together, before we started we discussed our different strengths to really get the best use out of everybody.
