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 use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

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 (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

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.

Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!

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

In this activity, learners are invited to imagine the park of their dreams!

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity, learners make self-assembled polymer spheres.

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.
