Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

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 physics activity, learners build their own rockets out of film canisters and construction paper.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

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 on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.

In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.

Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
