Snow Science
In this project we created, and tested a possible question about how to survive in the winter. This project mostly focused upon the ideal of heat transfer, and the property's of materials. We had to go through meany revisions to get to the point. My role in the group was to be the leader, and organizer. I lead the group in the writing, and in making sure the experiment will have results. I am not particularly proud of this, experiment, and I hope to do better next time.
The Rube Goldberg Project
The Rube Goldberg Project is based around learning physics of many simple physical mathematics, and putting them to work in one large machine. The reason why we built a rube goldberg is to further understand these concepts to help make them concrete by putting them to use. The requirements for this project are that in which is that the rube goldberg needs to work.
1. Must fit on a space roughly 2 ft. x 2ft x 3 ft (You can go outside of that for the start or finish step)
2. The contraption must be started with only one action, and must continue on its own for at least 20 seconds, and no more than two minutes. It must be able to be reset in a reasonable amount of time.
3. Must have at least 12 steps. A working step is defined as a triggering that causes an action. It is completed when one object transfers energy to another object.
4. Must have at least 2 different simple machines represented.
5. An object must be raised/projectiled at least 12 inches.
Our Rube Goldberg’s function is to launch a rocket, by being activated by a block of wood on a string, then flipping a switch. From there it turns on a motor which pulls a lever that hits a vertical switch, that then activates a small wench. From there the wench lifts up a wahit which letts a cart go down a ramp into a cup. THe cup is attached to a pulley system, which pulls another switch that turns on another motor. The motor pulls a string on a pulley, and pulls a wooden block up to let a whet down to hit a button which lounched a rocket.
I feel that our rube worked pretty well, it worked every time befor exhibition, but when exhibition came around the batteries didn't work because they don't work in the cold, which mad the the rube obsolete. Besides that it work fine. My contribution to the groups was that of a leader making sure we can get it done and have our rube goldberg done in time and making sure we are working.
