Explained is a representation of the three categories of spectra. Discusses what a lesson on spectra should include, background information, and equipment needed. Provided is a diagram of an absorption box. (RT)

Investigates the four week chemistry program in a summer program in science and mathematics. Identifies weekly topics for the program: (1) color and visible spectroscopy; (2) UV spectroscopy, fluorescence, and chemiluminescence; (3) IR and NMR spectroscopy; and (4) lists 12 individual projects. (MVL)

Addresses the requirements of high school students and noncrystallographers in lectures on crystals, diffraction, and structure analysis. Discusses basic understanding and a sequence that addresses these requirements. Suggests visual and descriptive teaching methods used in this effort. (CW)

Describes a procedure for constructing point groups based on the symmetric parent molecules of methane and adamantane. Intended for use in teaching concepts such as subgroups and cosets to beginners in group theory. (TW)

Uses the electron cloud and Lewis structure models to present resonance. Shows resonance bonding as an increase in dot density of the electron cloud. Provides classroom presentation ideas. (MVL)
