In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity, learners explore materials through paper chromatography.

This activity (on pages 15-23) combines interactive role-playing and graphing to introduce learners to the health affects of pollen.

In this activity, learners describe an object they can’t see. After someone picks outs a few mystery objects and places them in a pillowcase, learners will investigate using only their hands.

In this outdoor activity that can be combined with a hike, learners try to match a "mystery community" by shaking animals out of different trees and shrubs.

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

In this neuroscience activity (5th activity on the page), learners explore their sense of touch without using their senses of vision and hearing.

In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.
