What was the goal of this activity?
Our goal was to increase the time of impact and decrease force.
Our goal was to create an egg case that would increase the time of impact therefore decrease force of impact therefore, the egg won't break.
Describe your egg case.
No air resistance devices
Mass: 2 lbs. = .91kg
Dimensions: Less than .5m x .5m x .5m
My egg case was a shoe box divided into six different sections that had a bubble wrap layer as the foundation. The egg was set into a customized, singular egg carton that was constructed from a regular, dozen-egg carton. The interior sections supported the egg and the outside box protected the egg from the fall's impact. Each of the sections was packed with tightly, crumpled newspaper.
Did your egg break? Yes.
Explain why or why not.
Change in momentum equals impulse. Momentum is mass in motion and impulse is force exerted over a period of time. The change in momentum was the same for all the egg cases and so was mass. The egg cases had the same momentum, but mine had too much force exerted upon it that broke the egg inside. The impact was greater. Impulse is equal to force of impact x time of impact.
How could you improve your design? Or what new design would you use in the future.
The nails that I added for weight requirements could have poked --and broke-- my egg. When I measured and weighed my egg, I didn't have enough mass, so I had to add mass at the last minute. I used about 10 rocks and 15 nails in the final design. Next time I will be sure to have the right mass for my egg case.
