Egg Drop Contest
Hold an egg at ceiling's height. Drop it. What happens? Can you design a container that will prevent the egg from
breaking or cracking?
Let's make it more challenging -- let's use three eggs. And...let's restrict your volume. Now can you do it?
- To design and build a container with maximum volume that will prevent three uncooked eggs from breaking or cracking when dropped
from a height of approximately 2.5 m.
- To determine if the container is in freefall from calculations.
The container must be less than 2000 cubic centimeters in volume with no dimension greater than
25 cm. Maximum mass (including eggs) cannot exceed one kilogram.
Students must be able to remove the eggs after the container is dropped without damage. The eggs will be provided.
They will be Grade A large eggs. Remember -- you are using three eggs!
- Containers must be constructed prior to the school day of testing.
- A representative from each student lab group will bring the assembled container containing three eggs to the
instructor. All dimensions will be measured to ensure that none exceed the 25 cm maximum. The mass of the
container with eggs will be determined.
- A representative from the student lab group will drop the container (with eggs) from designated height (app.
2.5 m). A plastic tray will be provided to catch the container. Another representative from the lab group will be
positioned next to the tray. You do not want the container to bounce after landing!
- After the drop, the container will be opened. A representative of the student lab group will remove each egg.
Each will be examined for cracks or breakage.
- Student lab groups are responsible for cleaning up and removing all items from the lab area.
Egg Drop Form|

Students will record the time it takes their container to fall and the height
from which it was dropped.
Each student will use this form
to submit their project results.
