In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

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

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

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, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

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 colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

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

In this activity, learners cook amino acids and sugar to explore the range of aromas released.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

In the kitchen, learners can perform their own density investigation.
