Life in The Cold
The goal of this project was to create a scientific question and then carry out the experiment. Our experiment was to test out what clothing material would insulate the best in the cold. We carried out our experiment in two days and got our expected results. My role in this was to be the test subject. I had to stand in the snow in each jacket for seven minutes each. I was also the refiner so I went through and made all of the mistakes.
Rube Goldberg Project
This was our first major project in physics. My group members and I had to build a working rube goldberg machine. Our rube goldbergs main task was to make breakfast. The rube goldbergs had to have 12 complete steps. Our rube started by turning on the toaster. There was a string attached to the push butten that pulls down on a lever. The lever dropped a marble which then dropped a pulley. The pulley moves a small piece of wire which pushes a marble. The marble falls into a cup which then pulls the orange juice into the funnel. A clear tube is connected to the funnel which takes the orange juice to a cup. The weight on the bottem of the pulley pushes up another lever which drops a marble into a pvc tube. The marble hits a piece of tape. When the piece of tape comes off it drops a razer blade onto the butter and cuts it.
1. What hands on skills did you learn through working in your group? (construction, problem solving, collaboration, design, time management, etc...)
While working on this project I learned a lot of different ways to build things. I also learned that time management is very important
2. What steps were most challenging to make work? (How did you troubleshoot or redesign)
The step that was the hardest was the pulley. We had to move it around and mount it in many different places. Every time we had to move it we had to figure out the wieghting in relevance to to the weight of the cup. When figuring out where to put it we also had to put the cup to that the marble would land in it.
3. Explain the flow of energy throughout the whole rube from start to finish, (did it work all with just the input or did you add more along the way? In what ways is your rube efficient or NOT in transferring energy from one step to another)
It starts with downhill momentum from a pulley. It transfers then to a pulley which drops starting two more steps. The pulley moves a wire which drops a marble into a cup. The cup pulls the OJ off the top into the funnel and into the tube. The tube then spits it into the cup.
