Rube Goldberg
Explanation:
Someone fills a balloon with air. The balloon expands, causing two planes to rise. A track attached to each plain is lifted along with the plane. As the tracks rise, three marbles roll down track 1 and one marble rolls down track 2. The three marbles on track 1 are projected into a funnel. When those three marbles come out of the funnel, they fall onto another track. From this track, those three marbles knock into a can which then rolls down onto a slope. A string attached to the can is suspended on a pole and is also attached to the bottom of the handle of a measuring cup. As the can rolls farther down the slope, the string is pulled which causes the back end of the measuring cup to rise, allowing water to pour out from it into a funnel which then is distributed into a brewing machine. The marble on track 2 is projected into a tunnel. From that tunnel, that marble falls onto another track. That marble is projected into another tunnel which then lands on a plain. The plane is attached to a stick which is attached to the power button on the power stript in which the brewing machine is plugged into. As the marble falls onto the plain, the force causes the stick to press the button on the power strip, making it as well as the brewing machine turn on. As water is in the brewing machine and the power has been turned on, in a matter of time, the machine will produce a cup of tea.

Project Description:
The purpose of this project was to apply properties of physics to a single machine that completes a particular task. Our Rube Goldberg completed the task of making a cup of tea. The complex design of Rube Goldbergs allow for creative freedom while still requiring you to apply science to it to get a desired outcome. Our trigger was filling a balloon with air to lead to a course of actions that makes a cup of tea. The biggest challenge we faced was having group members in other classes. Due to this, most of our work on the project was done outside of school. Our original design for this project encompassed an excess amount of steps, but when we started the construction progress, we realized that building this project was going to take a lot longer than we though and we had to reduce the amount of steps it took to achieve our desired outcome.

E-mail vs. Letter Experiment
Reflection:
We did this project to learn how to design and complete our own experiments. I created this specific experiment because I was inspired by my penpals to discover which form of communication is more effective, e-mails or letters. I want to inform people about how they should go about presenting their information. The question that I generated to guide this experiment was: Does receiving an e-mail vs. receiving a letter effect how much you actually care about it's content? I have shown growth the most in gathering data as well as using a spreadsheet to analyse and organize data. It was quite the educational experience to go about collecting data on my own using human test subjects because all the other independent experiments I've done have not required me to collect data on other people. I also hadn't really used spreadsheets before coming to this class, so getting the opportunity to do put my data into a spreadsheet independently and presenting it has allowed me to learn for myself what to do.
