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 activity, learners turn empty 2-liter bottles into a see-through compost container.

Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

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

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 use their sense of smell to explore the world on the nanoscale.

In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

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.

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!
