In this video I explain and demonstrate how to build a Truss bridge. I used straws to build a Truss bridge but you can other materials. The Truss is easy to design and build in small groups. If you are a teacher using this video you can add constraints to make the Stem challenge harder. When testing the Truss bridge use 200-300 pennies in a cup and place the bridge between a 10 inch span.
Materials:
20-Non bendable straws
12 inches of tape
Scissors
