The Able Arch & the Trusty Truss

What makes arches and triangles so strong? Scouts will work collaboratively to learn about both the physical science and history of arch and truss bridges. Girls will perform five experiments to investigate the inherent strength of these shapes and discover why civil engineers frequently use them in the design and construction of structures in general and bridges in particular. Finally, Scouts will build a sturdy structure made out of triangles to take away with them.
