Feeling Bridge Forces

4th graders experimented with the feeling of the forces that a bridge has to endure by shaping bridges with their bodies.

“The arch bridge puts pressure on my hands and my feet move out far.  My shoulders are stretching”

“The cantilever bridge I could just hang out here. I feel pulling on my arms and hands but my feet don’t move because they are pushing together with the other part of the bridge. This is easier!”

 

“We can put our cantilevers together and make a huge bridge!”
