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

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 activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

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

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 and metals to explore single replacement reactions.

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