Building Bridges

The sixth grade students engineered, constructed, and tested truss bridges as an interdisciplinary math and science project.  West Point Bridge Builder, a free software program, allowed students to design a truss bridge on a computer and test it with a simulated load.  Analyzing the data from the computer program, teams of up to three students built a truss bridge using popsicle sticks and wood glue; the goal was to build a bridge with the highest strength-to-weight ratio.  

Congratulations to Lucas- the 2011 Truss Bridge Contest Winner!
