In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

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

In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.

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

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

Learners carefully look at four known household crystals.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.
