File Card Bridges

With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold. Besides step-by-step instructions for how to build the file card bridges, this activity also gives a brief introduction to the different kinds of bridges, along with examples (i.e., a log across a river is a beam bridge; the Golden Gate Bridge is a suspension bridge).
