This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this activity, learners investigate the properties of graphene and graphite.

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 discover if carbon dioxide has an effect on temperature.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

Make your own mummy! Using a combination of salts, transform an apple into a mummy and discover how the Ancient Egyptians used drying as one step in the mummification process.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

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

Heat makes some materials expand, and it makes others shrink.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
