Sweeteregg's Investigation Essay

I hypothesized that the helmet that would have the best results would be Ashley’s helmet. From judging the materials that she had used, I had estimated that her helmet would provide optimal protection for the egg. Her helmet was made of a very hard material for the main frame – which I thought would reduce any force. In addition, her helmet had a clear plastic covering for the front of the egg, which I thought would withstand all outside forces. The only vulnerability seemed to be the underside of the egg – which was clear on all of the egg helmets; however, her egg helmet was very heavy, thus giving me the impression that gravity would always pull the hard shell towards the ground. After testing, it was apparent that her helmet could withstand drops from tall heights; unfortunately, her egg helmet fell very short of having the best result. My hypothesis was accurate because her design provided an overall good protection for the egg.
I hypothesized that my helmet would be able to prevent Sweeteregg from cracking at a height of at least 1.5 metres. With the design that I had made for the
helmet, Sweeteregg was able to withstand distances higher than this during previous testing. Overall, the design I had created was very efficient considering Sweeteregg had attained a height of 2.25 metres. The outer, Styrofoam ball-like, shell had provided the most protection because the helmet would immediately roll upon contact with the ground – lessening the damage. In addition, the bubble wrap interior was useful because it reduced all impact that the egg may have been hit with internally. The only real flaw that my helmet seemed to have was the strap that held the egg in place. Despite it being able to effectively hold the egg within the helmet, the strap fell short in its ability to protect the underside of the egg. The strap Velcro-based strap with marshmallow and bubble wrap support was not enough to sustain the impact of a drop upon the underside. Overall, however, I still believe that my egg helmet was decently made, as it provided protection for the egg from almost all angles and it was able to dropped from a fairly tall height.

Part 4: Conclusion
1. State which group had the best results and why you feel this was the case.
The group that had the best results was Charlene and Cassandra’s.
I feel that their group had the best results because their helmet provided protection at more vulnerable spots than the other groups, including my own, and Ashley’s. Their helmet had a rubber base that covered more parts of the egg than other groups, thereby providing more protection – specifically on the underside. Almost every group had a successful top portion of the helmet – that was able to absorb impact; however, when it came to absorbing shock at the bottom of the egg, every group fell short but theirs. Furthermore, the rubber texture of the helmet allowed the egg to bounce upon impact, redirecting the force. Ultimately, their helmet held the egg tightly in place, and was able to protect the egg from great heights – including large flights of stairs. It is now evident why their egg helmet was so
successful.
