Egg Drop Lab Report
The purpose of the project is to understand how impact and impulse will affect an object, in this case an egg. We will have to design a box that will keep an egg from breaking when we drop it from three different lengths. I think that with the design that I was able to come up with my egg will not break from either of the three designated heights.
• Container (5inches×3inches×3inches)
• Plastic bag
The way that I designed my container for the egg drop will efficiently prevent the egg from breaking because of the materials. I chose to create a layer of air using a paper bag so that the egg would technically not hit the ground. Also because I thought it would give more room to absorb the impact from the crash when it landed. I chose to use Twinkies to cushion the egg because they are soft and will keep the egg in one spot. This would be helpful because the egg wouldn’t accidentally hit a spot where it would be unprotected.
With the design of my container I think it will protect the egg from most of the impact. Although I think that with the weight of the box the impact will be harder. The weight of the container will also decrease the time. With a decrease of time it will increase the impact of the box. Even with those two factors I still believe that the egg will survive because of the way I designed it.
