- "The Atom" videotape from the Ring of Truth series by Philip Morrison includes about a 3-min segment on the mole idea (reaction of different volume ratios of gases). Videotapes are available through PBS (800-424-7963). (To appreciate the entire tape, students probably need a broader understanding of chemistry than is held by the average student at the point in which development of the mole concept generally occurs in the high school chemistry course.) Essentially the entire text of the tape and all important visual images are also included in the book The Ring of Truth: An Inquiry Into How We Know What We Know by Philip and Phyllis Morrison (1987). PBS address (Ring of Truth):

- The video Powers of Ten goes from galaxy size down to nuclear size. It may help students visualize the size of atoms and the comparison of Avogadro's number in terms of powers of ten (Morrison, 1982). Video available from Video Catalog, P.O. Box 64428, St. Paul, MN 55164-0428 or High Bridge Co., 1000 Westgate Drive, St. Paul, MN 55114-1631.
- CHEM Study Video: Vol. 12, Gases and How They Combine. (1989). Illustrates Avogadro's Hypothesis (equal volumes of gases contain equal numbers of molecules). Available from Ward's Natural Science Establishment, Inc., P.O. Box 92912, Rochester, NY 14692-9978.
