Describes the latest stage in the design of an economical dielectric constant cell, tested in both instructional and research applications, that is suitable for student laboratories and for precision research measurements. (BT)

Expresses concern by chemists at Oakland University about the hazard of toxic substances, particularly as this concern is not shared by nonchemists in the occupational safety and health fields. Describes a four-year curriculum focused at producing occupational health generalists with a firm scientific foundation. (CS)

Discusses various methods the author has used in high school chemistry classes to maintain interest and keep grades at an acceptable standard. Integrated within the curriculum are research projects, library research, creative work, laboratory write-ups; a two-level curriculum is provided for nonscience and science majors. (CS)

Three demonstrations are described: (1) a variation of the iodine clock reaction in which a cassette tape recording of the William Tell Overture accompanies color changes as solutions are mixed; (2) a crystallization demonstration using sodium acetate; and (3) lecture-demonstrations creating colored colloidal dispersions from clear solutions. (CS)

Provides a list of the reactions commonly used for introductory kinetics studies. These reactions illustrate the kinetics concepts of rate law, rate constant, and reaction order. Describes a kinetic study of the hydrolysis of 3-bromo-3-phenylpropanoic acid which offers many educational advantages. (CS)
