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)
