In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

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.

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).

In this story time program, young learners listen to the Dr.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.
