Can we drop an egg without breaking it??
There are four main ways to help protect our egg (they could be combined):
- Wrap the egg in one or more materials
- Place the egg in a protective container
- Attach something to the egg to slow down the decent
- Place material on the ground to cushion the fall ß we won’t attempt this one for this project
You can choose 12 items/materials from the following list:
- 5 elastic bands
- 8 popsicle sticks
- 1 meter of clear tape
- 2 sheets of construction paper
- 1 plastic bag (grocery store)
- 10 straws
- 1 styrofoam cup
- Poster board
- 6 cotton pads
- 1 pair of socks
- Toilet paper
- 30 cm string
- 10 cm wires
- 2 balloons
- 1 paper plate
- 5 pieces of tissue paper
- 2 sheets of plastic wrap
- 2 sheets of aluminum foil
These materials are provided:
Phase 1: The Design
When you are designing this apparatus, there are a few things that you need to keep in mind. This device must be protective. The raw egg inside must not even crack at the first drop.
Phase 2: Testing
The project takes much trail and error and it is highly doubtful that you will succeed in your design on the first trial. You will most likely have to modify your current design or start completely over and design a new apparatus.
Phase 3: Actual Drop
Raw eggs are provided at the drop site. You should bring a small repair kit for your apparatus, i.e. tape, scissors, and left-over materials provided. Be fully prepared and bring all items to the drop site.
- An area approximately the size of a quarter of the egg must be visible at all times.
- Only the allowed materials may be used (listed above). Items can be negotiated and traded with other designers.
- Only raw, store bought chicken eggs may be used. Your design must not include changing the egg in any way (no tape on the egg, no soaking the egg in vinegar).
- The egg container and all materials must remain intact. For example, no parts—inside or out—can fall or break off during flight or impact.
- The container must be able to be opened once we return to the classroom so that we may check on the condition of the egg. The inside materials must be designed to allow the raw egg to be easily inserted and removed.
How your grade will be calculated:
Design & Explanation 15 points
Egg Contraption 40 points
Predictions about other designs 15 points
Surviving the first drop (approximately 3 meters) 15 points
Surviving the second drop (halfway up the stadium) 10 points BONUS
Surviving the third drop (from the top of the stadium) 20 points BONUS
After the egg drop test, answer the following questions in paragraph form, preferably typed.
- Describe how the contraption was assembled. (20 points)
- Were any materials exchanged?
- If so, which ones, how many, for what?
- Were any materials omitted?
- Provide an account of what happened during the experiment. (20 points)
- Include the mass of your project with the egg.
- Include the speed of the project and show all the math needed to calculate the results.
- Calculate the velocity, momentum, acceleration, and force of your contraption.
- All mathematical calculations should be written neatly on a separate sheet of paper and attached to the lab.
- What features did the contraption have to help protect the egg? (15 points)
- What did the egg look like after impact? (15 points)
- What worked (either in your project or others)? (15 points)
- What did not work (either in your project or others)? (15 points)
- List three things you would do differently if you could do this project again. (15 points)
This project is due on ____________________.
NO LATE PROJECTS ACCEPTED!!!!
- Select and print a scientific article from a reputable online source that has been published within the last six months OR select and cut out a scientific article from the newspaper or a magazine that has been published within the last month. The critical analysis must be printed and stapled to a copy of your article. (20 pts)
- Read the article and write a critical analysis. A critical analysis is different from a review you may write in an English class that is written for the general reader. Your journal article review is written for a specific reader (in this case, your teacher) who is knowledgeable in the discipline and is interested not just in the coverage and content of the article being reviewed, but also in your critical assessment of the ideas and argument that are being presented by the author. (50 pts)
- Use the following questions to engage with the article and help you form your critical analysis:
- Objectives: What does the article set out to do?
- Theory: Is there an explicit theoretical framework? If not, are there important theoretical assumptions?
- Concepts: What are the central concepts? Are they clearly defined?
- Argument: What is the central argument? Are there specific hypotheses?
- Method: What methods are employed to test these?
- Evidence: Is evidence provided? How adequate is it?
- Values: Are value positions clear or are they implicit?
- Literature: How does the work fit into the wider literature?
- Contribution: How well does the work advance our knowledge of the subject?
- Style: How clear is the author's language/style/expression?
- Conclusion: A brief overall assessment.
- The critical analysis should meet the following requirements: (20 pts)
- 1000-1500 words
- Typed using Times New Roman font
- 12-point font
- 1-inch margins
- Include the following in the “header” (single-spaced)
- Name of the article for which you are writing a critical analysis
- The analysis and a link to the online article you used (you will not have a link to send, if you find a scientific article from the newspaper or a magazine that has been published) must be submitted to TurnItIn.com before 7:45 AM the morning the analysis is due. This will be used to verify that your word count is in the acceptable range, as well as to ensure that there has been no plagiarizing. (10 pts)
