I had the best time volunteering in my daughter’s third grade classroom today. We talked about the different bridge types and after splitting up into groups, the students designed and started construction on their bridges. Check out the start of this cable-stayed bridge – which they sketched, measured and built together! They were all enthusiastic and wide-eyed about architecture, engineering and construction.
Best comment of the day, which was totally unsolicited, “the beam bridge wouldn’t be expensive to build because it’s the simplest shape and the least amount of pieces”.
This led the teacher into an activity of having the students list out the materials and quantities of each needed. At the end of the classroom project, the students will compare how much these structures would cost; ultimately showing which bridge type would be most economical. Oh, what they don’t know about Change Orders!
The class will continue to build and load test their bridges.
