Exploring Momentum: Egg Drop Project

Purpose: To explore concepts of momentum and collision by developing a container to lessen the force of impact when an egg is dropped from a high place.

Container Requirements: Make another egg case using any materials of your choosing. Your container may not be larger than 12 inches by 12 inches by 12 inches, and cannot weigh more than 1 lb. All other restrictions above apply.

You may not use any extensions that increase air resistance (parachutes, wings, streamers, etc)

The egg must remain in natural condition (fresh, not hardboiled), and you cannot alter the egg in any manner (painting, wrapping, taping, gluing, or any other shell reinforcements).

Report (Individual): 1. Describe the Egg Drop project and purpose. 2. Describe your egg case & include a detailed drawing w/ features labeled 3. What is momentum? 4. What is impulse? 5. Because of what you know about momentum and impulse, how can you lessen the force of impact (stopping force) on the egg? 6. Reflect on your design as an engineer would. How could you improve your design? What new design or materials would you try in the future? 7. Give one example of how what you learned in this project applies to a real life situation. Describe the scenario and how the principles of momentum and impulse work in that situation. 8. Complete Calculations page about momentum and the collision.

Points for Container:

______/ 20

Condition of Egg: 0 pts = projectile yoke streams at time of impact; explosive impact; egg violates rules 1 pt = complete and utter destruction of egg, with yolk exposed and shards of shell separated from egg 2 pts = leakage of a large amount of egg white, or small amounts of yolk 4 pts = small or larger cracks in egg, with leakage of small amount of egg white only 6 pts = hairline fracture cracks in egg 8 pts = eggshell has no cracks whatsoever Points for +2 points for being brave enough to participate!
