In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

In this activity, learners investigate the basic crystal structures that metal atoms form.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

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

In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

In this activity, learners are asked to examine the differences between two materials in a pair.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

Does yeast breathe? Find out by watching how plastic bags filled with yeast, warm water and different amounts of sugar change over time.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.
