Submarine SMASH Day Reflection

2/10/09
Today during smash day we were trying to build a periscope. Our mission was to use the periscope we made and see what things was in the box on a table. The only supplies that we are allowed to use was card board, paper, 4 mirrors, and scissors.
I am not sure how many times we had to modify our designs, because we kept changing it. Our group knew we had to change the design because we kept experimenting and when it did not work we knew we had to change it. We didn't exactly know what to do when we modify it we just went through trial and error. We communicated to each other by showing each other what we thought would work.
If someone was doing this for the first time my tip to them is just keep going through trial and error. Because i didn't succeed in this either.
