In this activity, learners explore sublimation by conducting experiments with dry ice.

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 chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.

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

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

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.

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.

In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

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

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.
