Sample forms are included (hazardous materials log sheet, laboratory class safety checklist, laboratory room safety checklist, injury accident report, noninjury accident report, and room…

Differentiates the tricarboxylic acid (TCA) cycle (or Krebs cycle) from glycolysis, and describes the bridge between the two as being the conversion of pyruvate into acetyl coenzyme A. Discusses the eight steps in the TCA cycle, the results of isotopic labeling experiments, and the net effects of the TCA cycle. (TW)

Describes a laboratory experiment in which benzene fluorescence is quenched by bis(acetylacetonato) copper(II). Discusses how this experiment can demonstrate a special technique used in the field of photochemistry. Provides an outline of the experimental procedure and discusses its results. (TW)

Discusses the concepts of relativity, mass, and energy, and the relationships between them. Argues that mass conservation inevitably follows from energy conservation. Proposes a scheme for introducing the laws relating to these concepts in general chemistry courses. (TW)

Describes a method of flow injection analysis intended for calculation of complex-formation and redox reaction stoichiometries based on a closed-loop configuration. The technique is suitable for use in undergraduate laboratories. Information is provided for equipment, materials, procedures, and sample results. (JM)

Although the crisis in precollege science and mathematics education has passed, various efforts are underway to improve the quality of education in these areas and to resolve existing problems. Several of these efforts are discussed, including the role of the National Science Foundation, industry role, and others. (JN)
