This Expand and Contract interactive also includes:
Gaps are essential to engineering bridges and roads. Learners watch a video showing a typical construction of a bridge to see why they're so important. They then manipulate an interactive to model the effects of temperature change on the bridge components. The importance of those gaps become apparent through the simulation.
