Rules: Please Read Carefully

Egg Drop Project

Objective: To create a container that will protect an uncooked egg from the impact of a 2nd story drop.

Directions: Each student (or pair of students) will design and build an egg container at home. On the drop day, Mrs. Nelson will provide one egg for each student. Each container will be dropped from the 2nd floor. Prizes will be awarded!

Rules: Please read carefully.

1. You may work on your own or with a partner. Outside help should be minimal (ie: your dad cannot design and build your project for you).

2. Your container must fit in a 12” x 12” x 12” box.

3. The mass of the container matters. A lighter container will get more points (see break down below).

4. Your container must fall to the ground. No parachutes, wings, or propellers (or anything else meant to increase air resistance).

5. No substance may be molded to form a “pod” or capsule around the egg. (No peanut butter,

jelly, goo, etc.)

6. No foreign substances may be applied to the egg itself.

7. You must build a container. No putting eggs in a big sponge or pillow and calling that your project.

8. Your egg must be secured inside your container. If the egg falls out during the drop you will lose points.

9. There must be easy access to the place where the egg will be located. No building will be allowed on drop day. You will only get 5 minutes to secure your egg in your container.

10. You have a budget of $10 MAX. You should use things around your house and only spend money if you really need to.

Any violation of the rules will result in loss of points. If a rule is unclear to you, please clarify BEFORE drop day. Project Steps and Points:

All work should be done on loose paper. On the Monday following drop day, you will assemble all portions and turn in. You may type your conclusion if you would like. This is worth a LAB grade.

1. Brainstorm (5pts): Prior to research, you must have at least a half page of ideas for possible designs and materials. This may include labeled sketches. Due Date: ______

2. Research (5pts): Use the internet to conduct research to inform your design decision. Submit a list of 5 websites (videos OK) and a brief summary (2-3 sentences per site) about what you learned from each site. Due Date: ______

3. Design (5pts): Create a labeled diagram for your top three design ideas. Write 2-3 sentences for each diagram explaining why you think each design will work and why you choose the specific materials. It’s OK if you end up changing your design along the way. Due Date: ______

4. Drop Day!! (23pts): Due Date: ______

a. All containers turned in on time will receive 10pts.

b. Each container will be measured and weighed prior to the drop.

b.i. Containers bigger than 12x12x12 will lose 2pts.

b.ii. Mass points: 5pts 0g

2pts 350g450g

c. Eggs which survive without any cracks will receive 10pts.

d. Eggs with only very small cracks (nothing dripping out) will receive 6pts.

e. Completely cracked or smashed eggs will receive 4pts.

f. If the egg falls out of the container, you will lose 2pts.

g. Any other violation of the rules will result in the loss of 2pts/violation.

Bonus Points (+2 each)

**Lightest Surviving Containers (2 from each class)**Best Design** Most Creative Container

** Most Spectacular Crash**Most Durable** 5. Conclusion (12pts): In 3-5 paragraphs discuss the following (you may type this)

a. Summarize how you decided upon your final design. How did your research influence your design? Explain how you built your container and any issues you came upon as you were building. Did you do any practice drops before drop day?

b. What happened on drop day? Why do you think your container had this result? If you could do this project again, what would you change, and why?

c. Discuss the physics behind your egg’s freefall. Explain how concepts such as force, velocity, mass, position, time and acceleration were components of this project. Underline each of the bolded words in your conclusion. This is an important part of your conclusion. Take your time explaining the physics behind the project and do quality work. (**I will award more points for this section**) Bonus points for including some or all of the following: FBD, net force equations, calculations, %error (AP)
