Identify the Problem
The problem is that we need to find a way to keep an egg safe when a weight is dropped on it using crumple zone technology and paper.
Generate Ideas
-Fold paper into a spring shape top absorb impact. There would be many layers of these.
-Fold paper into a box shape and make lots of them and make a cube out of them.
-Roll paper into a tight roll and then stack them into shape of a cube.

Research
-Crumple zones are areas of a car that are meant to crush when hit and absorb the impact during a crash.
-Most crumple zones incorporate a honeycomb design.
-Crumple zones work best when they are spread over an area.
-Crumple zones distribute the force away from the passengers in the car.

Possible Solutions
-The possible solution I chose was to make the paper into a spring shape and then layer them into a cube. This is similar to the honey comb shape used by modern cars.
Matrix
Reflection
My group ended up choosing my design (spring made with triangles) because it showed that it had lots of compression when hit by something thanks to the springs in it. It was also quite durable and although was the heaviest was not actually that heavy.
Graphical Model
Results
My groups design showing that it works as planned.
1. How does the weight impact the crumple zone?
The data has shown that the lighter the crumple zone the more likely it is to work. The heavier it is the more likely it will get a maybe. The no's are hard to describe because some of them are extremely light while others are extremely heavy.

3. What makes a good crumple zone?
A good crumple zone is one that absorbs the impact of the object it is being hit by. It should collapse on itself and basically just "crumple" to stop the thing it is trying to protect from getting hurt.
