A group of 3rd graders were amazed when they were introduced to their challenge. They all knew that bridges were made of wood, steel, concrete and logs but when they were told they only have paper and the to use, many thought it could never be done. Their teamwork and dedication paid off as all groups were able to construct a bridge using the unusual materials. The structure not only had to look like a bridge, it had to function as one too. It had to past a weight test (5 pound book), a car traveling over the bridge and a boat going under the bridge. It took several tries for some students, but in the end they all learned a few things about construction and the Scientific Method.
