Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about
