Bridges: Paper Bridges and Suspension Bridges

A bridge must support its own weight as well as the weight of anything placed on it.  Our fourth graders made two types of bridges. A paper bridge which they created with only one sheet of paper, 5 paper clips and 2 blocks of wood and then tested its stability. They also created a beam bridge (then transformed it into a suspension bridge) using  straws, tape, paper clips, and a paper cup. Their engineering skills and creativity were evident with these challenges!

* I enjoyed this challenge. The beam bridge was the harder of the two bridges to make. - Citlali, Fred Douglas
* I learned that you have to support the bridge in order for it to be stable. - Justin, Fred Douglas
