EGG CRUMPLE ZONE PROJECT
Identify The Problem
The problem is that the egg will be crushed with no crumble zone.
Generate Ideas
Some brainstorming includes:
- Make small balls the size of thumbnail.
- Make small poles sticking up.
- A cube filled with poles on their side.
- A cube filled with small balls.
Constraints
This problem is limited to me because:
- We are limited to only using paper.
- We are only able to use a three inch by three inch area.
- The weights are getting heavier each drop.
- The crumple zones need to be light.
Criteria
Some other factors that influence our choice include:
- Weight
- Thickness
- Size
- Time
- Compressibility
- Sturdiness
Research
Research I found include:
- If the crumple zone is too hard, the crumple zone will not crumple and crush the egg.
- If the crumple zone is too soft, the weight will go right through it and it will crush the egg.
- The prototype I made was a little too hard so I will try to make it a little softer if possible.
- It takes 25 newtons to crack and egg.
- A spring does not only absorb the impact but it launches the energy back or it transfers the energy.
Possible Solutions
My possible solution is:
I chose this solution because I noticed in my prototype, that only the poles on the bottom take most of the impact. The poles on the top don't do anything so I am going to replace them with balls to absorb the impact more.
- A box full of half balls and half poles on their side.

Data Collection
- The average weight of the crumple zones was 17.2 grams. My crumple zone weighed 18 grams, .8 above the class average.
- The average weight of my groups crumple zones was 18.75 grams. Mine was lighter than the average by only .75 grams.
- The average weight of the yes crumple zones was 18.65 grams. Compared to mine, it was .65 grams heavier.
- The average weight of the maybe crumple zones was 14.75 grams. Mine was 3.25 grams heavier.
- The average weight of the no crumple zone was 9 grams. Mine was 9 grams heavier.
Data Questions
- The weight of the crumple zone impacts the crumple zone because it's all about density. If you have a very light box with nothing in it, the box may get crushed and will have no impact on the apposing force. If the box is small but very heavy, it may have too much stuff in it. It could be like a brick instead of an object made to take the impact.
2. Things that make a good crumple zone include light weight and if its able to stand the impact.
