Describes how the continuous variation method may be used in senior chemistry classes at the secondary level. This technique allows for the detection of the one or more reactions that may occur in a system over a wide range of composition. (JR)

Discusses the conduct of a general inorganic chemistry course in a community junior college with emphases upon students' participation and interests. Included are a list of proposed topics and two samples of evaluation sheet. (CC)

Discusses the Environmental Protection Agency report on the economic impacts of clean water on industries and municipal sewage treatment works. Concludes that the long-term growth of the industry may be slightly impaired, but market trends, technological advances, and productivity will far overshadow these impacts. (CC)

Discusses a unique experimental program for training chemical technicians in New York with emphasis upon expansion of minority participation in sciences. Included are descriptions of goals, educational methods, instructional materials, and program's content. (CC)

Discusses the use of a new approach, rather than quantum mechanics, to obtain practical solutions to bond energy problems. Indicates that the complex nature of mathematics and the small magnitude of bond energies involved in an approximation are two practical impossibilities for quantum mechanics to reach simple, reliable results. (CC)

Discusses various control techniques used in chemical processes, including measuring devices, controller functions, control valves, and feedforward and feedback actions. Applications of control to a real chemical plant are exemplified. (CC)

Presents three reasons that graduate education in chemistry must change, such as social irrelevancy, propensity for specialization and isolation, and neglect of product quality. Suggests reestablishment of a better university-industry relationship and encouragement of greater student participation, more individual expression, and wide talent…

Discusses the use of the "extent of reaction" in teaching freshman honors classes of elementary chemistry to provide students with a unifying concept in the treatment of stoichiometry. Four sample problems are included. (CC)

Discusses the case of DDT which can be introduced to nonscience students in a chemistry course, including the development of DDT, problems associated with its adverse effects, and curtailment of its use in our environments. (CC)

Discusses the development of new curriculum materials for use in the preparation of chemical technicians in two-year community colleges and technical institutes. Indicates that the texts developed are equally suitable for the chemical part of environmental programs and medical and engineering technician curricula. (CC)
