This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.

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.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

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.

"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?
