The London Bridge should not have fallen down. And here's why. After a brief history of bridges and the three main types, class members are introduce to the concepts of tension and compression, the two main forces acting upon bridges. 

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

Students examine the bridges of Washington State. They focus on the suspension bridge between Tacoma and Gig Harbor. They see how three different types of bridges work by rotating students through bridge stations.

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Students view examples of suspension bridges and discuss their structure. They complete a tension and compression experiment with a partner then perform a similar experiment with books. They discuss engineers and how they design and...

Students build a model of a suspension bridge and test the amount of weight it support. They identify different types of bridges: suspension, arch, girder, truss, cantilever, cable-stayed and moveable.
