Rube Goldberg Project
Project Description:
In groups of 3, we designed and built a complex contraption that performs a simple task. In addition, we demonstrated the application physics concepts and supported this with calculations to explain the motion or transfer of energy for each step. For this project we were required to learn about rube goldbergs and how they work. The goal of our rube was to flip a bottle, a trend where you flip a bottle flips all the way around and lands right side up. We had to have 12 steps. In the end, our rube only worked if the floor was still, and at the exhibiton the floor wasnt still, so it needed some assistance. Questions: 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 design things, problem solve and time management. I also learned how to use a drill bit. 2. What steps were most challenging to make work? (How did you troubleshoot or redesign) The pulley and the bottle flipping part. We had to try over and over to make the bottle flip. 6. Personally what was your biggest contribution to the project? I think the biggest thing I contributed was the overall paperwork, (ie the analysis). |

Life in the Cold Project
Project Description:
For this project, we were supposed to pick out a different thing that you would need to survive in the cold, my group chose to build a shelter. Our experiment, was to see what color would absorb the most sun and make the shelter the warmest. We tested pink, black and white. Our hypothesis was "If the color of a material affects the shelter, then we think that the black sheet will affect it the most because dark colors absorb the most heat." and our question was "How does the color of a material used to build a fort affect insulation? " In the end we figured out that black can absorb every wavelength of light, light is connected to heat which results in black containing the wavelength of light while white reflects it. This is due to the result of electromagnetic waves. Darker colors absorb more heat because they can absorb all wavelengths of light and convert them into heat. Overall the black sheet kept it the warmest.
