In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.

In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.

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.

Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.

Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.

In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i

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 experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this activity, learners explore reaction time and challenge themselves to improve their coordination. Do you want to move faster? Catch that ball that you never seem to see in time?

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.

In two separate bags, learners mix water with Epsom salts and detergent.

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 challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

In this activity, learners create and reveal secret messages written with invisible ink! The invisible ink is actually a baking soda solution, and the magical revealing liquid is fruit juice.
