Then there were the 6th grade bridges. We knew this class was amazing and creative and it certainly showed in their bridges: some designs that had never been tried before in the history of this project! Teams of students work together to create blueprints and a model of a bridge, in addition to each student's business letter responding to the call for bids on a bridge, and their bid price, based on their estimates. It is a math block: lots of record keeping for supplies (toothpicks and glue), check-writing, interest-rate calculations, payments for workers and engineers, healthcare percentages, etc. 
Jonas's team, Sky High Engineers, created a suspension bridge. The first!

And then the bridges are tested out to see how much weight they can hold. It's not all about the weight though: they are graded on craftsmanship and beauty as well. A five-gallon bucket is suspended from the center of the bridge and water is added, one yogurt container at a time, as the eager audience counts in anticipation! Lots of excitement.

Do you see in that picture, above, that there is one full bucket already? Crazy, right? Notice the tightly held anchors (the nylon thread), pulled so very taut.
I think they filled TWO buckets....


...Before she finally gave way! (Sky High Engineers were the winners for weight!)
