My group planning process was pretty efficient. From the start we knew the direction we wanted to take. We were well aware that our time to think of a successful plan was limited (25 min.) Two feet of tape and 8 straws were very difficult supplies to make a strong outer protected layer without covering 50% of the egg. As a group, we believed the best approach was to make a cubic outer layer with a reinforced inner layer with the egg in the absolute middle. The tough part was figuring out how to get a hold of the only scissors in the class. One of us came up with the idea to send someone out of the classroom to look for a pair of scissors. This saved us a significant amount of time and effort. One negative part of our planning that we had was that we did not account for the weakness in the tape. This made the process much harder to formulate. We cut pieces of paper to visualize the straws. We also, used those straw length pieces of paper as a guide to see how we would build the protected cube. One of our biggest dilemmas was the lack of time. We knew that we only had 10 minutes to build the object once we received the supplies, however, it was quit a procedure to handle the speed of the development. Each person in our team had a different job. Two people were making the straws into cube-like figures. One person was in charge of the egg and keeping it stable so that it would not break. Another person was in charge of the scissors, so that no one steals it. During the building process, we realized the tape that we were using was not strong, so it caused us to use up more time to reinforce the structure with extra tape. I believe that our planning was done pretty well, however, our group did not account for physics. When an object falls the most dense area will hit the bottom first especially when thrown from 10 feet high. Because, we did not have time to tape a straw cushion both on top of the egg and under the egg we decided to spend the rest of our time supporting the area under the egg. When the time was up, the area under the egg was well cushioned, but the area that was more dense was not protected. When our team member dropped the figure, even though she dropped the figure with the unprotected side facing up, the more densed area hit the ground first and broke the egg. Therefore, it is safe to say that if we had another minute or two to secure the top part of the object we would be successful in fully protecting the egg from breaking.
