Isolating the Variable

During today's Science Class, we tested our boats that we made out of 3 sheets of paper, 3 straws, and a meter of tape. We were assigned to make a boat that could withstand as many weights as possible. The weights were meant to be students crossing a "moat" which was actually our school fish pond. We were "supposed" to be attacked by chocolate missiles that would turn us into chocolate popsicles if we were shot.We all used the same materials, the same weights and the same water levels without any currents. Only the design of the boat was tested, for everything else was the same.

The uncontrolled variable of the assignment was being able to design whatever container you want. This did affect the outcome of the project because it differed in how many "students" could fit on the boat and whether the boat could withstand the weight.
