a) We had mutual feelings of a 50-50% chance that our "machine" would work. We were a little behind time so we had to rush to finish. We eventually got it working pretty consistently leading us to believe it would work. Luckily, when it was our testing time it did.
b) On Wednesday, Ryan Libby contributed by marking the heights of the ramps for 30cm, 50cm, and 70cm. Will McCaddon contributed by making the perfect pulley system so the water bottle filled with seeds would drop directly into another bucket launching a weight upwards to hit a ramp. Bobby Buell contributed by making sure as the marble went down a funnel into a tube it would be able to hit a domino then he made sure the domino would set off the rest of the dominos leading to the rat trap pulling the water bottle into the bucket. Finally, I (Austin Koehler) contributed to making sure we met all the requirements. I pulled up the rubric and checked to make sure we had all the simple machines needed, energy transformations, etc.
c) Yes we have filled out all requirements. We had everything we needed in our project. We were not missing any simple machines (we had more than needed) and we also had all energy transformations, some happening more than once.
