Egg Project Requirements
Transportation Unit - Automobile Safety
Automobile safety is an issue that has implications for all students. Students will learn about Newton’s Laws and how they apply to automobiles and automobile safety, shock absorption properties of various materials, transportation systems, bumpers, active and passive restraint systems and engineering design and problem solving in the automobile safety context.
1. You and your partner must design and build a CO2 powered wheeled vehicle that will allow you to move a hard boiled egg (driver) from point A to point B as shown in class. The device must have a bumper “system” made from two or more shock absorbent materials. It must have a “restraint system” for the “driver”. The “driver” MUST be able to “see” in all directions. The final product must show quality workmanship in design and construction.
2. You may not touch the device or egg after it leaves point “A” and the egg must remain unbroken and must not "leave" the vehicle.
3. The device must travel along a guide-line over a smooth surface for approximately 22 feet and protect the egg from breakage when the device hits a wooden wall at the end of the run.
4. Along with design and quality workmanship, the speed of the device and its ability to protect the "occupant" are the most important factors.
5. You may use tools and materials that are available in the Tech ed shop or you may bring in material from outside.
6. You will be supplied with a special base to hold a CO2 cartridge. You must also note the special height requirement that your device must meet in order to fit in the launcher.
7. You will be allowed two trial runs with real eggs. After each trial run you will be able to modify (re-engineer) your device so that it will meet the requirements.
8. A final run will be done for a grade, you will calculate the speed of your vehicle in MPH and complete a grade sheet.
9. ***You can use any material you choose to solve this problem however the design and overall look of the vehicle is an extremely important part of your grade. No part of the bumper may touch the floor or guide wire. Also, the egg is the driver of this vehicle. You may do anything to the egg that a driver would do in a real passenger car or race car. Finally, as the driver the egg MUST be able to see forward/backwards and sideways at all times.
PROBLEM SOLVING: You must use a problem solving approach to find a solution to this problem. Before any construction begins your team must present :
1. A printout of your “brainstorming” “problem solving” “research” on Google Docs
2. Evidence that you tested at least one material, using our computerized testing device, to determine it's ability to absorb shock. You MUST use that material as your first bumper.
3. A sketch of your proposed device with all dimensions and parts labeled
4. You must also give a verbal explanation of how it will work. If approved, you may then begin construction
PROCEDURES TO FOLLOW:
1. Carefully construct your device according to your proposal.
2. Feel free to make modifications and changes as you build and encounter obstacles
3. Conduct two “test runs” make modifications
4. Work safely with all tools
5. Prepare for the “Final Run”
Vermont Framework of Standards
PURPOSE: The purpose of this task is to apply technology education skills that you have learned to apply knowledge and understanding of technological systems to respond to a number of issues and to design solutions to problems as outlined in the Vermont Framework sections:

Final Project Grade
Fill out Engagement and Focus Habits of Work Rubric
TOTAL POINTS ___________
Advanced- 95-100 Proficient – 85-94 Emerging- 75-84 Beginning – Below 74
*FEEDBACK: *Based on your observations of your device and the way it performed, describe any changes you would make in your vehicle if you were asked to do this same project again. Write this paper as if you were handing it in to your language arts teacher for a grade and include it in your PLP under the Applied Academics section.
