Hop into the science lab and teach your class the chemistry involved in the making of makeup!

In this lesson from DragonflyTV, Jazi and Danielle become cosmetics chemists, experimenting with combinations of ingredients to create batches of lip gloss. After they each create an initial batch using different quantities of the same ingredients, the girls modify their "recipes" to alter characteristics, including hardness, color, and shine. The girls then test-market their formulations, asking members of the public to apply and comment on the three choices. Based on the results, they determine whose formulation is preferable.

Students can use this chemistry investigation as a science fair project idea:
