Rube Goldberg project In our first semester we learned about mechanical advantages such as pulleys and levers. The Rube Goldberg's were suppose to run at least 20 seconds. I feel like this was fun project, it was just frustrating at times. Our Rube Goldberg was made to make breakfast for our audience. The breakfast we were planning on making was buttered toast and orange juice. We started it by pushing the toaster lever down which pulled a box over with a marble in it. The marble rolled down are track and landed in a cup which was on pulleys. When it lands in the cup it trigger another marble to fall into a cup and when the cup falls, it pulls over a cup of orange juice into a funnel then the orange juice runs down a tube and into a cup. The marbles wait in the cup made the cup go down and made a weight come up and knock a lever which had a marble in it that landed on a track and hit a duct taped string that made a knife fall and it cuts the butter. 1. What hands on skills did you learn through working in your group? (construction, problem solving, collaboration, design, time management, etc...) I learned how to put stuff together in different ways. In the beginning I would just come up with an idea and and just make it how I thought it would be, but it wouldnt look nice and it would barely be held together. When we got more in depth in the project and if one of us came up with an idea we would figure out a better way to put it together so it is actually sturdy. 2. What steps were most challenging to make work? (How did you troubleshoot or redesign) The step that was most challenging was were a marble rolls down are track and drops into the cup and the cum lowers and when it lowers it knocks a little box which drops a marble onto a small track that has to go down. That was the hard part, getting the marble to land on the narrow track. We had to make the small track closer to the actual box that drops the marble. We also made the wooden box more narrow the the marble couldn't roll around and stay straight as it falls onto the track. 6. Personally what was your biggest contribution to the project? I think my contribution to this project was coming up with new ideas and building some of are steps. |

Project Description: We were learning about heat, so for are project we decided to make a shelter and see if snow could hold in heat better than no snow on the shelter. The reason we picked this project was because we were just working on heat. Snow is cold so would that make the shelter colder, or would the snow be able to keep your body heat in the shelter better?
The roles I played for this project:
My roles were researcher and procedure, but we really didn't do are jobs by are selfs. We would help each other with each thing we had to do.
