For this project, I was partnered with Ethan Rapp. We decided to build a container that would prevent an egg from breaking if it fell. What we did for this project was pick a previous project we did that year (or something similar to it) and make it work better. We decided to do an egg drop as it is similar to the physics of sports because it involves acceleration, force, etc.
Physics
Our egg has a weight of .25 pounds. Using this, we can find the force that it hits the ground, without air resistance.
F=ma
F=(.113lbs.)(9.8m/s^2)
F=1.1074N
We can also find the velocity, using the formula:
V=d/t
V=(5m)(4s)
V=20m/s

Today we got started on our egg drop project. We came up with the basic idea to tie rubber bands around the egg and suspend it in the air of the box. We ended the day with half the box ready.

Today we finished our box. We didn’t have an egg, so we worked making the box better. We tightened the rubber bands.

We finally brought an egg. We put in in the rubber band hold and went outside. We threw it up into the air and it did not break. We then went to the bleachers and threw the egg off. It did not fall out. We knew we had to do it multiple times to make sure the egg would work. We threw it a second time and the egg was smashed to bits. We had to start over because the yolk of the egg was all over the cardboard.

We made our new cardboard box and brought a new egg. We knew how to make the cardboard box this time, so we just made that. We didn’t have any time to drop the egg, so we finished class by putting our stuff away.
Thursday, June 4, 2015
We went outside and we through our egg off the bleachers and it hit a bar and exploded. We then had to make a new project. We came back to the class with just enough time to make the cardboard protection box again.

We went outside to test our project again. It broke on the first throw. It fell down multiple steps, so that was probably why it broke. We had to clean the track so we spent most of the class cleaning. After, Colin decided to finish it at home, which he did.

Reflection:
This project was a lot harder than I had thought it would be. Ethan and I worked well with each other, but we had different ideas about how the egg drop would work. We decided to make a topless box like the one in the picture above. The egg would fit in the strings. It is tight so the egg would be nice and snug.
