In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?

In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this activity, learners experiment with how dish soap and fat interact by making a colorful swirl.

In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

In this biology activity (page 8 of the PDF), learners will explore how saliva assists in the beginning of the digestive process.

In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.
