Describes two courses in chemical safety required as a part of a two-year program in chemical technology offered by the Northern Alberta Institute of Technology (Canada). Lists the topics covered in each course. Provides descriptions of hand-outs, audiovisual materials, demonstrations, assignments, and examinations used in the courses. (TW)

Proposes that the production of alcohol from corn be used as a practical application of scientific principles that deal with energy transformations. Discusses the solar energy available for growth, examining the utilization of solar energy by plants. Describes the conversion of corn to alcohol, with suggestions for classroom and laboratory study.…

Discusses the use of two different computer applications to teaching college chemistry. Describes the "electric laboratory notebook" (ELN) courseware and its use in an instrumental analysis course. Provides an overview of the use of commercial spreadsheet programs in the chemistry laboratory. (TW)

Describes a course offered at the United States Coast Guard Academy that deals with the marine transportation of hazardous materials. Outlines the major topics covered in the course, including marine transportation regulations. Discusses the use of lectures, laboratory demonstrations, and "hands-on" activities in the instructional sequences. (TW)

Discusses the diversity of names used for various types of polymeric materials. Concentrates on the naming of linear organic polymers. Delineates these polymers by discussing common names, source-based names, characteristic group names, and structure-based names. Introduces the specifications of tacticity and geometric isomerism. (TW)

Discusses the production and use of polymer materials as thermal insulators. Lists several materials that provide varying degrees of insulation. Describes the production of polymer foam and focuses on the major applications of polystyrene foam, polyurethane foam, and polyisocyanurate foam. (TW)

Lists eight sources of technical information suitable for classroom use which deal with polymer materials. Provides the names and addresses of these societies and associations and describes the type of information each has available. (TW)

Suggests a method for solving verbal problems in chemistry using a linguistic algorithm that is partly adapted from two artificial intelligence languages. Provides examples of problems solved using the mental concepts of translation, rotation, mirror image symmetry, superpositioning, disjoininng, and conjoining. (TW)

Discusses the advantages of conducting online computer searches of "Chemical Abstracts." Introduces the logical sequences involved in searching an online database. Explains Boolean logic, proximity operators, truncation, searchable fields, and command language, as they relate to the use of online searches in undergraduate chemistry programs. (TW)

Discusses some of the chemical concepts that the United States Space Program illustrates. Describes ways to use the space program to motivate students to learn chemistry and its relationship to the world. Provides examples of classroom applications to environmental chemistry and biochemistry in studying the operation of the space shuttle. (TW)

Discusses the dependencies of people on chemicals in various aspects of life. Describes some of the natural and synthetic chemicals currently used in food production, clothing, shelter, travel and exploration, sports and recreation, ventilation, heating and cooling, communications, decoration, sanitation, and education. (TW)

Describes two laboratory demonstrations in chemistry. One uses dry ice, freon, and freezer bags to demonstrate volume changes, vapor-liquid equilibrium, a simulation of a rain forest, and vaporization. The other uses the clock reaction technique to illustrate fast reactions and kinetic problems in releasing carbon dioxide during respiration. (TW)

Describes several techniques to help students visualize the principles of polymer chemistry. Outlines demonstrations using simple materials (such as pop-it beads, thread, and wire) to illustrate the size of macromolecules, the composition of copolymers, and the concept of molecular mass. (TW)

Background information and procedures are provided for experiments in which the zinc and strontium content in bones (fossils and/or fresh mammalian samples) is analyzed to determine relative amounts of animal and vegetable foods consumed by an individual during its lifetime. (JN)

Reports results of experiments favoring use of 0.5 percent nitric acid with an oxidant (potassium dichromate or potassium permanganate) to preserve samples in polyethylene containers for mercury analysis. Includes procedures used and statistical data obtained from the experiments. (JN)
