In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

"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.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

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

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

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

"Molecules in Motion" explores how materials behave and change in a vacuum.

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

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

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