This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.
