In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

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

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

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

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

"Nature of Dye" allows participants to create their own dyes and art while exploring how chemicals interact and how these interactions can have real-world applications.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this activity, learners explore materials through paper chromatography.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.
