Winter Concert Photo Project


On these pages we show you some common bridge designs and describe their structure. We have photos of famous bridge designs. Then we describe a contest that allows students to build a bridge from toothpicks, following strict design rules. We even include a simple formula for determining the winner of such a contest! Also included are instructions for students on how to get started with their bridge, bridge designs using marshmallows, and a virtual bridge building page, where you can experiment with toothpick designs right here on your computer!
