Introduce students to structural engineering and bridge structures with this simple and affordable teacher’s guide. Hands-on activities help students learn about the physical concepts of tension, compression, bending and buckling; mathematical concepts such as length, area, volume and scale; and time and monetary constraints related to bridge building. The guide includes reproducible templates, step-by-step instructions and illustrations to build several types of bridges, including a 3-span beam bridge, suspension bridge and drawbridge.
