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 explore the relative size of the Sun and Earth as well as the distance between them.

This is a classic exercise for visualizing the scale of the Solar System.

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, learners explore how distance can affect the way we perceive the size of an object.
