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

In this Cyberchase activity, learners make carpenter's squares and use them to measure square corners. Learners cut out the carpenter's square template and attach it to tagboard.

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

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 make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.

Build a house you can fit inside, using cardboard tubes.

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.
