Marking+Period+1+Project

Welcome to Science and Tech!! We welcome our first project of the year as the Rube Goldberg Project. Here it is!!! Rube Goldberg was a cartoonist who designed complicated multi-step contraptions that did very simple tasks. One that you may be familiar with is the Mousetrap game. You will be required to design, build, and demonstrate one that will do one of the following:

1. Trap a Mouse 2. Extinguish a candle 3. Waking a Sleeping person(ALARM) 4. Raise a Flag 5. Your choice (must be approved) This may be done by yourself or with a partner of you choice. Choose wisely!

Criteria:

1. The design must contain a minimum of four different simple machines. One of the simple machines must be using gears. Each of the machines must transfer energy in your demonstration. Energy Transfers & Machines must be **labeled** on both blueprints and device. Determine the mechanical advantage of each machine in your project.

2. **DUE: ?** TO BE INCLUDED IN PLANS: a. An explanation of how your device transfers energy in each step (10pts) b. A labeled drawing of your device clearly showing start/stop and each machine (10 points)

3. **DUE:??** : device materials/ or revisions. a. If revisions are required – step two needs to be handed back in for reevaluation. b. ALL Students will hand in an explanation of the materials used for the machine (15 points)

4. The actual device must be constructed from the approved plan and be constructed of **junk**. It should be **colorful** and cannot be larger than 2 x 2 x 2.

5. You will present your project to the class. a. Identify the different simple machines and their placement. b. Clearly show the labeled MA of the various machines. c. Clearly describe how the device will work prior to demonstration. d. Demonstrate the use of the device.

I will allow one class period in order for you to work on a rough copy of your design. You will need to construct your project outside of school. Be creative, but plan to use “stuff” from around the house. Presentations will be ??? . Good lucK Check out the worddoc ! and Rubric
