Clay Bridges

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building. Key learning ideas are that bridges must support their own weight as well as any additional forces, and longer structures can become unstable at the ends. An extension is to use more or less clay and observe the effects.
