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 group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.
