Chemistry

Use this video to familiarize students with the properties of acids and bases. Beginning with an overview of how these two kinds of chemicals react to or neutralize each other, the program explores Arrhenius’s ideas on ion release and Lowry and Bronsted’s theory of proton exchange. Details on the pH scale, indicators, conjugate bases, and Lowry-Bronsted reactions are featured along with numerous examples of acid and base applications: cleaning agents, electric batteries, stomach antacids, and indicators in analytical chemistry experiments. Viewers will find the video’s lively demonstrations and their use of everyday objects and materials particularly helpful. Viewable/printable educational resources are available online. (31 minutes)

This program demonstrates the changeability of solids, liquids, and gases with real-world, easy-to-understand examples. Set at a campsite, the video utilizes simple tools at hand—a camp stove, pots and pans, boiling water, and ice—to explain the concepts of state change, latent heat, expansion, contraction, and sublimation. Viewers will become familiar with the particle theory of matter, how heat or cold changes the characteristics of a wide variety of materials, and how a great deal of technology relies on these transformations. Helpful animation sequences and concise chapter summaries reinforce essential physics and chemistry concepts. Viewable/printable educational resources are available online. (28 minutes)

Very little in the physical world occurs without chemical reactions being involved. This program takes an in-depth look at five common products—soap, polystyrene, aluminum, paint, and car batteries—and explores the chemistry behind their manufacture and use. With the help of graphics and footage from inside manufacturing plants, the video reveals just how surface chemistry, redox chemistry, metals, and polymers play a part in everyday life.
