Describes a course, including content, reading list, and presentation on chemical reactors at Cambridge University, England. A brief comparison of chemical engineering education between the United States and England is also given. (JN)

This article describes recent progress in chemical synthesis which depends on comparable advances in other areas of chemistry. Analysis and theories of chemical structure and reactions are determinants in progress in chemical synthesis and are described also. (Author/SA)

The polarization of organized labor v environmentalists on the political scene is discussed. The angry workers claim that environmentalists in their zeal for cleaning up the air and water and protecting wildlife are throwing people out of work. (Author/SA)

Described is a procedure for the study of condensation polymerisation. The objectives of this study are to help students understand concepts that are somewhat abstract in nature (i.e., polymerisation) through derivation of equations that help to describe and predict the particular phenomena. (CS)

Deals with trends arising from decreasing amount of descriptive chemistry being taught. A course outline is suggested, and general and specific aims are mentioned. Some detailed examples of models of thought, which should replace theories, are suggested and the future of syllabi is briefly discussed. (Author/JN)

Describes the use of infrared and atomic absorption spectrometry in an introductory chemical oceanography course to introduce students to carbonate mineralogy by having them determine both the crystal structure and the magnesium content of seashells that they have collected. (Author/JN)

Lists the materials and describes two procedures, for demonstrating the solubility and complex ion equilibrium of silver(I) compounds. Indicates possible hazards and proper disposal. Suggests several homework problems. (JN)

Presents an experiment involving photochemical legand displacement on a metal carbonyl, separation of the product mixture by chromotography, and identification of the components by use of infrared spectroscopy and group theory. The chromatography and spectroscopy are combined as complementary tools in this experiment. (Author/JN)

Described is the use of analogy in teaching abstract chemical concepts. A foreign universe is postulated and nuts, bolts, and washers play the roles of atoms and molecules in this universe. (DS)

A National Research Council report has recommended practices for safe handling and disposal of hazardous chemicals in laboratories. They are a practical alternative to detailed regulations on individual chemicals. Topics discussed include physical hazards, chemical hazards, chronic hazards, laboratory ventalation, protective equipment,…

Presents a curriculum that attempts to foster responsible, decision-making capacities in senior high school or undergraduate freshman students with respect to the use of hashish and marijuana. (CS)

Described is an interdisciplinary science course in speleology. Topics include geology, biology, chemistry, physics, and mathematics associated with speleology. The general outline of the course and a reference source list is included. (DS)

Described is an activity centered interdisciplinary science course made up of one investigation from the area of astronomy, geology, chemistry, biology, and physics. Each investigation requires different techniques, preparation and analysis. (DS)

Reviews the history, nomenclature, theoretical background, and construction of batteries. Compares the performance of different battery types. (JN)

Presents information intended to encourage students to become thoughtful consumers. Discusses the role of pepsin in splitting off amino acids from stomach proteins and the nature of the protein substrate in determining the ph at which pepsin operates. Directions for an experiment are included. (Author/SA)
