In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

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 chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this chemistry activity, learners use yeast and hydrogen peroxide to generate a gas (oxygen) and test some of its properties.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

Learners build a small rocket using a matchstick and a piece of aluminum foil. A second, lit match launches the match rocket. This activity involves fire; adult supervision required.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this chemistry activity, learners use mossy zinc (or a galvanized nail) and hydrochloric acid to generate hydrogen gas and test some of its properties.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

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