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

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

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 mark their height on a height chart and discover how tall they are in nanometers.

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.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

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.
