Journal Entry (9)

9/2/10: Today we fixed the car and it worked for the first half of class but then it broke again :(. We also worked on our experiment again. We figured out that we had a couple flaws in our experiment such as we only tested once for each tire and we didn't have a big enough variety of tires. Over the weekend we are going to get bigger wheels and smaller wheels than we already have and test them at least 5 times each.
