Bridging the space between farm and table

As part of the study of harvest, students in the Bumblebees class engineered and constructed bridges that a vehicle could drive on to transport the harvest from the farm over a river and to a store or market. They chose the bridge-building materials. Some materials were more successful than others. This activity carried far beyond the day of the lesson and bridges continue daily to be designed and constructed and tested. This friend said the trickiest part was making sure the bridge was sturdy.

This friend thought it was difficult to come up with a new design when the first design didn't work.  

This friend said he found himself worrying about the bridge breaking even when it didn't when tested.

This friend said the trickiest part was keeping the ramps from falling down.

This friend felt his biggest challenge was designing a smooth ramp. 

This friend found his ramps were too heavy and tended to knock down his bridge. Bumblebees revised their construction, sharing ideas of what worked and what didn't to help their produce get to market.
