In this activity, learners explore acids and bases by preparing six solutions that combine vinegar and ammonia, ranging from acid (all vinegar) to base (all ammonia).

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

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).

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners investigate vitamin C.

Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.

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 activity, learners electrically plate zinc onto brass objects.

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 activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

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.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this activity, learners will experiment with salt and ice in order to turn a bag of ingredients into ice cream.

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

In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.
