In teams, students will act as civil engineers and build a segmental bridge model. Instead of building it out of concrete, which is messy and needs a few weeks to harden, they will use Styrofoam. Styrofoam is a weaker material than concrete, so instead of having to use special steel cables, a small diameter bungee cord will do.

Build a model segmental bridge and test the model to understand some behavior attributes of segmental bridges such as deflection.
NGSS Disciplinary Core Ideas
ETS.HS.1C.a Criteria may need to be broken down into simpler ones that can be approached systematically, and decisions about the priority of certain criteria over others (trade-offs) may be needed.
Common Core Standards
