In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties. They observe changes in size, skin...

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together. They also create plans...

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk. Using food coloring and soap, they discover that milk is an emulsion, a special...

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon. This reaction shows the...

Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder. They can lift their prints with clear tape,...

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch. Learners test cream of tartar, baking soda, lemon...

In this physics activity, learners build their own rockets out of film canisters and construction paper. Learners discover how a chemical reaction (from a mix of water and Alka-Seltzer) creates gas...

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle. Though this activity was...
