Egg Drop Project
Goal: The goal of this project is to design a ‘vehicle’ that will allow an egg to be dropped out of the classroom window and land in the courtyard intact.
Rules:
- The device must fit into a box that is NO MORE THAN 20cm tall, 20cm wide, and 20cm long. (It can be smaller, but NOT larger)
- NO PARACHUTE
- The egg must be easily removable such that it can be inspected for cracks. You will have 60 seconds to reload your egg into your vehicle after inspection.
- You must have a small Ziploc bag to put the egg in so if it breaks it does not make a mess.
- At least 1/3 of the egg must be visible! (think windshield/window/sunroof)
- You CAN NOT completely wrap your egg or just dig a hole in foam and place your egg in it. YOU MUST CONSTRUCT SOMETHING.
Checklist:
Research: Two article found and discussed in background.
Design:
o Sketch drawn, labeled, and explained
o Materials list
o Timeline
o Build pictures (at least 5) with captions and explanations
Launch:
o Ziploc bag
Conclusion
o Discussions of successes and failures and possible modifications
Overall Project
o Total project neat/organized/ and TYPED
o Works cited for all research articles
Project:
Your project will be completed as if it were a research and design portfolio for a company looking to buy a line of egg drop devices. You are trying to SELL your project so all aspects should look professional and be fully explained.
Research and Background:
This part of your portfolio proposes and explains the theory of momentum and impulse. It reflects on the research that you read and HOW those ideas influenced your design ideas. It also includes the formulas that govern impulse and momentum. You should refer directly to the articles you read and include a WORKS CITED for anything you look up!
Design Plan:
This part of your portfolio proposes a vehicle design. It will include a sketch of the design with the materials labeled. Underneath, there should be an explanation of each ‘safety’ feature you chose to design and why you chose to add this feature. Most of these reasons should come from personal experience or the research you did. You should also have a list of the materials you used, and a proposed build timeline.
Build:
This should chronicle the actual building process. Include a series of at least 5 pictures and captions that explain to your reader the steps you took to build your vehicle. If you make any changes in your original design, you should explain those changes during this chronicle.
Drop:
You will get points for the height you egg survives from. Must have a Ziploc bag for your egg.
Conclusion:
In this section you will reflect on the overall process and the actual performance of your vehicle. Comment on anything in the research process that you would have done different. Also comment on all aspects of the design that were successful and give an explanation as to why. Then comment on things you would improve on next time. If aspects didn’t work, explain how you might fix them. If your design did work, remember you are trying to sell this to someone. Come up with ways to make your design either more cost effective or more aesthetically pleasing.
TIME LINE: the following are DUE dates!
Friday (2/5)
Research
- Find 2 articles regarding 2 different safety features (cars, sports equipment…) Read each article and answer the following questions on a separate piece of paper.
o What is the purpose of each safety feature?
o What physical quantities (time, speed, mass, force, momentum, impulse…) are effected by the safety features you are describing and HOW!?
o How would it be different if the safety feature was not built into the device? (again, talk in terms of the physical quantities mentioned above)
Monday (2/8)
Design
- Using the ideas you read about and the ideas you heard in class, start designing your egg drop vehicle. Remember to keep the rules in mind. Your sketch should have labels and look neat and organized.
o Each feature should have a label and an explanation as to what you hope that feature will do in terms of the physical quantities mentioned above.
Wednesday (2/10)
Materials
- You will come up with a list of the materials that you will need to complete your build and a detailed timeline you hope to follow.
Friday (2/12) – Sunday (2/21)
Build
- This is your build time. You will be asked to chronicle your build with pictures and captions to explain what you are making and if you had to make any changes to your initial plan and WHY.
Monday (2/22)
Drop Day!
- You will need to bring in your completed and ready vehicle and a Ziploc bag. Your device will be dropped from three heights (assuming it survives).
o The first will be my eye level
o The second will be from the ceiling of the classroom
o The third will be out of our classroom window.
- You only move onto the next height if your egg does not crack or break on the previous drop. Remember, you egg must be easily removable and reloadable after every drop.
Tuesday (2/23)-Thursday (2/25)
Analysis
- You will spend tonight analyzing the success of your vehicle. You will finish your proposal with an analysis of the parts of your design that worked well and those that failed. You should include why you think they either worked or didn’t, and how you could improve the failures. If your device worked well, you should include ways to make your device lighter or more cost effective because remember, you are trying to sell this produce to a company.
Friday (2/26)
Whole project DUE
- The whole project is due. Neatly organized and well written. This is a portfolio you should be proud of. It should look like you could hand it to a business and they would trust your design and want to buy your vehicle.
Rubric for your Typed Report:
Component / points3 / 2 / 1 / 0
Goal / Goal is nicely stated and introduced as if you are trying to sell your project / Goal is restated in my original words / Not there
Research/ Background / Well organized and includes all theories on impulse and momentum in your own words. Examples in real life are given, and ideas from the reading are referred to. All formulas and quantities are introduced with their units. / Somewhat organized, theories are restated but not explained in your own words. Only one example is given and there is little reference to the reading done. Formulas and units are incomplete / Not organized. Theories are misunderstood. There are no real life examples or referenced to the articles. Formulas are missing / Not there
Design Plan / Sketch is neat and professional looking. All features are neatly labeled and explained with reference to the articles read. Materials list is well organized and timeline is organized and achievable. / Sketch is neat but not completely labeled. Explanations of key features are missing or incomplete. Materials list is incomplete and timeline is not well organized or planned out. / Sketch is slopping and labels are missing. There are little explanations or they are incorrect. Materials list and timeline are incomplete. / Not there
Build / There is a nice organized progression of pictures with captions explaining key features/build steps. Any changes from the original plan made are acknowledged and explained. / There are some pictures of the build, but not enough. Some photos have captions, but explanations are lacking. The build does not follow the design plan, but some of the changes are accounted for. / There are few pictures and captions are missing. There are no explanations of changes made. / Not there
Conclusion / Well organized conclusion addressing all successful and failing components of the design. Ideas are offered on how to make it even better. There are clear relations back to the readings on the theories of impulse and momentum. / Somewhat organized. Some aspects of the vehicle were analyzed, but key features were missing. There is little reflection back on the readings and how the vehicle could be improved next time. Little mention of momentum and impulse theory / Poorly written with few reflections on the success of the design. No mention of the theories of momentum and impulse and no suggestions for the future / Not there
Drop / Survived from the window / Survived from the ceiling / Survived from eyelevel / Did not survive at all
Rules Followed / All rules were followed / One rule was broken / Two rules were broken / Three or rules were broken
