MSL Bridge Building with Marshmallows



I had the honor of judging a bridge building competition today. The eighth grade contingent of the Math, Science and Leadership program at the Institute were asked to build bridge structures using toothpicks and mini marshmallows. The bridges then had to withstand several books being piled on top one after the other until the structure collapsed. When they had used all the books from the set they had bought, a water jug was used to additional heft.

Bridges were judged not only on how well they withstood the pressure, but also for original design and efficiency in the use of the materials. The one bridge which stood the longest was reinforced many times over with additional toothpicks and many mini marshmallows. The structure which ultimately was judged the best was constructed out of a lattice of pyramids reversed on themselves.



Cindy from the business school was the other judge, and it we independently were in agreement on all of our picks.

Well done eighth graders.
