Build that Bridge

For my first Action project in my class Urban planning, we were able to build a bridge using only 65 popsicle sticks and Elmer's glue. The goal was for it to hold 10 lbs without breaking. This ties in with what we're learning because in the first unit, we learned about the purpose of bridges and how they have to do with urban planning. My classmates and I took a field experience on a city walk downtown with the Metropolitan Planning Council. We saw different buildings and bridges and how that affects the citizens of Chicago. On that tour, we saw draw bridges, they let up in the middle so that boats can come through. This experience also related to SDG goal 11 ( Make cities and human settlements inclusive, safe, resilient and sustainable ) because we learned more about how structure and architecture has to do with accessibility. For this Project, our bridge had to be a truss bridge. A truss bridge is a type of bridge that has a structure composed of triangles.

I worked with my classmates CM and OL, and we decided to build a truss bridge inspired by the Pratt bridge. During that process, we observed the law of conservation of energy, we didn't create nor destroy energy because everything we designed transferred into something even when it eventually broke.
