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

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 activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

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

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

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.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

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

In this chemistry activity (on page 2 of the PDF), learners corrode a penny in a cup with vinegar, salt water, and a source of iron (nails, paper clips, or twist ties).

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

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

This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.
