Building Bridges

Inspired by their study of Roman bridges, 2nd, 3rd, and 4th Graders designed and built their own truss bridges. They investigated the elements and physics behind load, tension, and compression, and learned about the central role that triangles play in producing a durable bridge. After drawing blueprints, students measured, marked, and re-measured pieces of balsa wood before teachers cut their requests. Construction was a multi-week project and the children's commitment paid off when they were able to test the surprising load strength of their bridges.

Please note also in this photograph the huge amount of snow in our playground and also the bilingual Spanish-English notation for playground. Such bilingual signs are found through out the classrooms, aiding in Spanish vocabulary acquisition.
