Although I have made a number of adaptations to this project, the basic concept is excellent as written. (Example of adaptation: we make it non-competitive by setting a target weight for bridges to hold instead of testing all bridges to destruction. Everyone can feel successful, not just the team with the strongest bridge.) Students in middle school can learn a lot about structures, measurement, budgeting, planning, design, and teamwork from this activity. It's always one that our fifth and sixth grade students at The Miquon School recall fondly years later. Although it is presented in the book's title as a math activity, we use it as part of a larger study of structures in social studies -- a good way to cross discipline boundaries.
