RUBE GOLDBERG:
Project Description:
The Rube Goldberg Project requirements were; in groups of three design then build a complex contraption that completes a simple task. Along with that we also needed to have the physics typed guide. Also by the end of the project we needed to have a video showing each step on our rube.
Our rubes final step was to press a button for a popcorn machine, our first step was just a marble rolling down a track then hitting a domino, which then triggered other dominoes. Then that triggered a ball to free fall and hit progressive dominoes. Next, the progressive dominoes triggered a pulley that then made a weight slide down a wire to hit a big marble the go down a track. While that was going on with the weight going down the wire above it was a marble rolling down steps then hitting a bigger and heavier ball that then went down a track to free fall and hit the button to the popcorn machine.
REFLECTION:
1.What steps were most challenging to make work? (How did you troubleshoot or redesign)
The step with the wire and the weight, we had to keep fixing the wire to make sure it was perfect and right where it needed to be. We finally got it to the position we wanted it and it worked well!
2. 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)
The rube would not work at times so we ended up having to add more adjustments and change some of the steps.
3. What one physics concept from your analysis is most important to the overall function of your rube?
The most important physics concept that is most important to our rube is probably Conservation of Momentum in a Collision. We had many collisions.
4. What was the hardest part of doing this project, how did you persevere?
I think that the hardest part of doing this project was finishing it and having everything done before exhibition. The night before exhibition after school my group and I worked on finishing all of the construction and testing it to make sure it would work, and I did many times at exhibition!
5. Personally what was your biggest contribution to the project?
My biggest contribution to the project was helping and doing a great amount of work on both the analysis as well as the rube construction process. I think that we all as a group contributed a good amount.

LIFE IN THE COLD: Surviving and Thriving in a Winter Environment
Project Description:
This Projects essential question was; How does the structure and properties of materials affect their ability to absorb and transmit heat? How do we apply these understandings to maximize our ability to survive and thrive in the cold? We formed a group of four people and came up with our own question as a group. The question was; How does the color of a material used to build a fort affect insulation? So our group decided that we would build a fort and test out three different colored sheets.
Procedure:
In order to test how colors affect the retention of heat in a shelter, we will make a shelters using a tarp and sticks. In order to test our independent variable we will get three different color of sheets and put them over the shelter. In the shelter there will be a cup of boiling water. We will test the temperature before and after. The water will be in the shelter for 15 minutes at a time with a different colored sheet every time we test it, every 15 minutes. In that amount of time we will put a thermometer in the cup and keep track of our time and temperature change.
