Bridges

Spanning across time—well, maybe not time. Using simple materials, teams design, draw, and then construct a bridge. Teams build the strongest, safest, and most economical bridge using the materials from the supply price list. Each team member should create a design before deciding as a group which one to build. Teams then test the strength of their designs by determine the amount of weight it can hold.
