In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

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 discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

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 investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

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 discover that a material can act differently when it's nanometer-sized.

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

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

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