A river for you to build a bridge over.

All the parts you need to make a bridge demonstrating how arches work, the importance of keystones and how surprisingly stable the arch shape is even without cement! Finally the pack contains the parts you need to investigate strength in simple beam bridges; which shapes are strong? Which make the best bridges? All you will need is cardboard to print the parts onto, scissors and glue for assembly.
