    I think for MS kids, especially in grade 6, doing what you did makes sense. Let them explore and brainstorm before adding constraints. It promotes creative thinking and makes failing safer. The quality control of materials is an excellent idea.I did pasta bridge building once via MYP Design. It was in grade 8. We tried to quantify scoring via an efficiency equation:Score (Higher is Better) = Mass Bridge Supported Right Before Failure *TIMES* Bridge Span /then DIVIDED BY/ Bridge Mass Bridge span was the distance between the supports at each end. I recall one student took the risk of scoring higher by increasing the span. His thinking was solid and his bridge failed spectacularly.Making a plate to sit on the bridge from which to hang the weight receptacle was tricky for us. Our bridges span…

Our bridges spanned between two tables and needed to be higher to be appreciated--what you did with the 2x4s was smart.Thanks for sharing your lesson and the learning.
