After testing each bridge, our students found the accordion bridge with the beams on the top and bottom would hold the heaviest loads! We learned the more support the bridge has, the heavier the load it can handle. We also talked about the importance of engineers building bridges correctly, as it can have disastrous results! (Check out the video of Gallopin' Gertie to see an example!)
