In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

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

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

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

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.

In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.

In this activity (pages 8-9), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
