A) I believe we will be successful because we have put a lot of time and effort fine tuning our Rube Goldberg so no minor errors will occur.
B) Grant mounted some more rails, Z made the base more sturdy and reliable, Nate covered the loose screws, and I (Cameron) put together the mouse trap and pulleys system to cue the balls launch.
C) Yes, we have fulfilled all of the projects requirements and we have identified all machines and energy transfers.

Group #33 day 5
A) When we presented the project it was not successful. We were unable to get our mouse trap to set and we were unable to release our golf ball.
B) We would for sure need to plan more a head of time and plan our working better.
C) We learned how to use tools better, we learned about angles and measurements, and we learned about doing better for our planning skills.

Group 25- Day 5
A. We were unsuccessful in our official test, but were successful in unofficial tests on our own. We were unsuccessful because our marble got stuck inside of one of the tubes and in between a crevice connecting two ramps.
B. Spend more time connecting tubes and ramps because if not connected properly, the marble is not able to roll smoothly and leads to experimental error.
C. We learned that a pulley does not actually have a mechanical advantage unless it is connected to another pulley. We also learned that it best to draw out a blueprint first to know how to assign projects and time. Lastly, we learned the different placements possible for a fulcrum in a lever.

a) The simple machines we plan to use are levers, screws, pulleys, and incline planes. We will use levers for dominoes to set off a mouse trap and then also to release the golf ball. We will use pulleys to turn on the light and to raise a weight to hit the golf ball down the ramp. We will use screws to hold the golf ball in place. Lastly, we will use incline planes to slow the marble down.
b) The energy transformations we will use are GPE, KE, Chemical to electrical, and then gravitational energy to kinetic. GPE is used when the marble rolled down the planes. Chemical to electrical is used when batteries turned on a light.
c) Bobby Buell made the lever for the marble and contributed during his free periods. Will McCaddon planned out the launching incline planes and came during his free's. Ryan Libby made the mouse trap and the water bottle filled with bird seed. Austin Koehler made the weight in which the bottle lifted it to hit the lever.

Group 5 Post 5
A) We were successful in our testing, I think it is because of the hard work we put in at 6:30am to 8:45 on the testing day. The day before we had it down, but that was our time to make sure it was perfect.
B) Some changes I would have made would be to make the dominos higher up, it would have allowed for an easier machine below because we could only go so low; the table space ran out.
C) 1-Planning 2-Organization 3-Reliance on members of the group

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.

a) The changes my group adapted to from our original design was almost our whole thing. When we begun building, our original outline became too complex so we had to compromise. Examples of changes we had to make from the original design was taking our idea of a weight turning a fan on. We could not make it work so we decided to figure out something else to use.
b) Other major problem we ran into was organization, people in our group being in different physics periods, and time management. However, organization fell into people being in different periods. This was stressful because three of us had the same period so we could work together while one of us had to work alone. With the schedules working out like that, it made it hard to explain to the person by themselves what they should do.
c) Besides energy transfers and simple machines, two other physics concepts we had present in our project were velocity and speed. These go hand in hand together. As the golf ball for instance got pushed down a ramp, the speed went up and so did the velocity. Also, when our water bottle hit the light shooting up the weight to hit a ramp, the velocity was high enough to turn on the light.
