This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

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.
