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.

In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.
