Life in the cold:
In this project we designed a project that would help you survive out in the cold. Together as a group we we figured out a experimental question. Our question was: How thickness of insulation affects heat retention? The reason behind this experiment is to see which type of installation would be useful when surviving in the cold. The bottle representing body heat and the different types of thickness representing fabric use when surviving in the cold. When you are in the cold and need something to keep warm you need something with down insulation and good fibers. In these groups we each had a role to take place in this experiment, my role was the data manager and documenter. The main part of my job is to making sure all the data is recorded .
Rube Goldberg Project:
For this project we built and showcased our rube goldberg machines. A rube goldberg is when you have a series of obstacles complete a simple task. As a class we used the physics concepts that we learned to create our very own rube goldberg machines.The requirements for this project was that there has to be twelve steps explaining kinetic and potential energy also having efficiency. Other requirements for this project is that it has dimensions of 2 ft x 2ft x 3ft. Also, it had to work all on its own after the first step and continue without assistance. Our rube was having it paint splatter on a canvas. the rube starts off with a car going down a ramp, the car hits a block that swings. The block that swings hits a domino. After this step there is a domino effect the last domino hits a ball bearing that begins rolling toward a ramp that knocks off a marble. The marble rolls down a ramp then continues onto a teeter totter to roll up then down onto a ramp underneath it. The marble then rolls down the ramp to come out through a whole. Another domino effect happens. A marble is then knocked by the very last domino, the marble releases down a tube. (This tube later turning into a track is very important because it connects the steps at the top of the rube with the steps at the bottom of the rube). Once the marble comes out of the tube, it hits a heavier marble causing that to roll onto a track that leads right to a mouse trap. When the mouse trap springs from the weight of the marble the string that is caught in the mouse trap with a bolt releases. This string is connected to a pulley holding weights that fall onto the tubes of paint exploding onto the canvas
- What hands on skills did you learn through working in your group? (construction, problem solving, collaboration, design, time management, etc...)
- What steps were most challenging to make work? (How did you troubleshoot or redesign)
- Personally what was your biggest contribution to the project?
