Describes an experiment in which luminescence is observed during a reaction between sodium borohydride and trisbipyridalruthenium (III). Includes a discussion of the theory of chemiluminescence. (MLH)

Suggests replacing traditional organic chemistry laboratory exercises with experiments involving an elementary research approach. The student is provided with short laboratory projects, normally involving simple reactants and products; it is an important criterion that the reactions chosen are not normally featured in student textbooks. (MLH)

Various taped exercises relating to selected chapters of the textbook "Salut" (Diesterweg, Frankfurt) are presented and discussed. The exercises were created because the drills in the textbook seemed too monotonous to the students. (Text is in German.) (IFS/WGA)

Describes the use of videotapes to eliminate or shorten in-lab instruction and prevent interruption of a laboratory session with additional or forgotten instruction. Lists equipment needed for videotape programs and for a thirteen unit audio-visual laboratory. (GS)

Traces the historical development of the university instructional laboratory. Describes the basic components of a problem-oriented laboratory program and identifies four forces that may dictate instructional change in the future. (GS)

Describes an experiment in which possible products of a series of reactions are tabulated together with properties which may be useful in identifying each substance. The student deduces the products and writes a balanced chemical equation for the reaction. (GS)

Describes a course designed to provide college juniors and seniors with maximum theoretical and practical exposure to every available analytical instrument. (GS)

Describes an experiment which monitors the population of the lowest triplet state by directly observing phosphorescence intensity as a function of time. Reviews the theory concerning triplet state lifetimes, describes the experimental apparatus and procedure, and presents the method and examples of data analysis. (GS)

Describes a course for which laboratory manual/text was written utilizing discovery-type experiments. Students investigate personal protection monitors, radioactive emissions, and the nature of radioactivity. (GS)

Explains a series of experiments that increased students' awareness and understanding of activation energy, reaction transition states, rates of reaction, provided a neat example of the diagnostic utility of infrared spectroscopy and furnished insight into the accidental research situation. (Author/GS)

Describes a laboratory course in Physical Geology designed to encourage students to ask their own questions and to develop and test their own answers. The essence of this approach lies in providing a minimum of preconditioning before the exercises. (MLH)
