Egg Drop Project


Objective: This is an individual project to be done at home. You are to make or build something that is the lightest possible weight, and yet durable enough to protect an egg thrown off the swimming pool roof so that the egg doesn't break from the fall. Think of the egg as a passenger in a car going through a crash test.

A - Egg survives the fall fully intact
B - Egg is cracked, but intact
C - Egg is broken
E - Project is not done or disqualified

Description: This is a lab which you and your team will design a casing that will allow an egg to hit the ground safely. The casing will be thrown at full force from a second story window directly at the pavement.

Materials: Anything goes long as rules #1, #2, and #3 are not violated.


1.) Your team will receive one grade and so each team member is responsible for contributing to the design phase, the building phase, and the written report.

2.) Your grade will be based on the three criteria: A.) The quality of your design. B.) The quality of your initial and final reports. C.) Your eggs success at survival D.) If your egg cracks but does not break, points will be deducted. E.) If your egg breaks, a grade of "incomplete" will be recorded until success is achieved.

3.) Bonus points will be awarded for: A.) Creativity and simplicity of design B.) Limited use of soft "fluffy" material


Start by brainstorming with your team and come up with a few sketches and plains on paper first. (It is suggested that you have a backup design in case your first design does not work.) By the end of the period, you must write a primary report on the computer and then pass in a hard copy of this report. To save this report on the computer, name this report using group member's first names and then save it in the "Egg Slam" folder in the "Dr. Fonare" folder in the "My Documents" folder on the desktop.


The initial report will include:

A.) Title page listing all team members, the period and date, and appropriate title.

B.) A sketch of your preliminary design.

C.) Material list.

D.) Approximate measures.

E.) An explanation of why you think your design will be successful


The final report will:

1.) Title page listing all team members, the period and date, and an appropriate title.

2.) Detailed sketch of the design with a complete description of components.

3.) Explanation of the physics involved in your design and the reason for the survival of your egg.

4.) Your evaluation of the outcome. What could you do differently that might improve design.



  • Maximum size of cargo create: 20 cm x 20 cm x 30 cm.
  • The egg must be fresh; it cannot be boiled, frozen or coated with polish, glue, paint etc.
  • No packing materials (bubble wrap, Styrofoam, peanuts, etc.) No towels, soft cloth, cotton balls, sponges, etc. No food products.
  • Of course the egg and its contraption must hit the ground! I will be doing the throwing, and I'll throw them anyway I want!
  • No balloons or parachutes are allowed.
  • The egg and the project must weigh less than 200 grams. ( the average egg weighs 50 grams)
  • Only raw, store bought chicken eggs; size medium or larger may be used. You may NOT soak the egg in vinegar.
  • Your egg project must fit on a regular size sheet of paper. (note that it may be 3 ft high and still fit on the paper)
  • Your egg project must have an opening the size of my pinky finger where i can see a portion of the egg.
  • You may not use nerf balls, pillows, or stuffed animals to protect your egg.
  • You may bring in your project early to weigh it - if your project is overweight you may take it home and make any neccesary alterations. If you wait until the last minute and your project is overweight, it will be disqualified.
  • Once a project is in school it may not be touched by anyone other than its owner. Please have your name and class period written on it.
  • Once a project has hit the ground it will your responsibility to retrieve your egg and show it to the score keeper for scoring.
