Many chemical reactions are reversible, and the forward and backward reactions can occur at the same time. When the rate of the forward reaction is equal to the rate of the backward reaction, we call that a dynamic equilibrium. We will learn how equilibrium can be described by the equilibrium constant K, and how different factors than can affect the chemical equilibrium.
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

The ACS Education Division is making educational resources available by topic to aid parents and teachers in student enrichment during this time of distance learning. We have bundled materials from the Reactions Video series, C&EN, our magazines within the Education Division and our portfolio of hands-on activities for students in grades K–12 and beyond. These resources focus on five topics — The Earth, Water, Food, Health & Your Body, and The Periodic Table — and put a spotlight on the connection between chemistry and everyday life.

This lesson has students solving the mystery of a note by conducting chromatography. They will test different washable markers and see that different marker colors are made up of various pigments. They will compare and contrast the note chromatography with other chromatography results from a variety of markers.

Polymers are a vital part of our everyday lives and nearly all consumer products have a plastic component of some variation. Students explore the basic characteristics of polymers through the introduction of two polymer categories: thermoplastics and thermosets. During teacher demos, students observe the unique behaviors of thermoplastics. The fundamentals of thermoset polymers are discussed, preparing them to conduct the associated activity in which they create their own thermoset materials and mechanically test them. At the conclusion of this lesson-activity pair, students understand the basics of thermoplastics and thermosets, which may entice their interest in polymer engineering.
