In response to a question, "Why not use a magnetic or electric field to deflect light?," reviews the relation between electric charge and electric/magnetic fields. Discusses the Faraday effect, (describing matter as an intermediary in the rotation of the place of polarization) and other apparent interactions of light with electric/magnetic fields.…

Results from two surveys of chemists and educators conducted at two conventions indicate weak spots in facilities, poor storage information, and failure to take precautions against reactive hazards. Includes suggestions and a checklist related to a wide range of storage problems. (SK)

Background information and laboratory procedures are provided for an undergraduate experiment requiring students to prepare a coordination compound. (SK)

Describes an advanced simulation illustrating how basic engineering skills can be combined with economic considerations and risk-taking judgments to effectively design and operate a chemical processing unit in a competitive environment. The simulation is used as one of five projects in a technical management course. (SK)

The possibility of changing the prosaic style of college level science textbooks to increase readability was investigated. Conclusions suggest that the readability of college textbook prose is not significantly affected by the stylistic factors employed in most readability formulas. (CJ)

Examined relation between college students' (N=108) ability to solve simple ratio tasks (for example, their proportional reasoning patterns) and their rule-governed behavior with the balance beam. Also identified modifications in a set of rules for the balance beam tasks. Results and implications for science instruction are discussed. (JN)

Suggests that science-related material on nuclear war be included in introductory courses. Lists nuclear war topics for physics, psychology, sociology, biology/ecology, chemistry, geography, geology/meteorology, mathematics, and medical science. Also lists 11 lectures on nuclear physics which include nuclear war topics. (JN)

Discusses topics on membrane electrodes corresponding to approximately six hours of lecture time. These include glass, liquid, crystal, gas-sensing membrane electrodes as well as enzyme and other bioselective membrane electrodes. Instructional strategies and other topics which might be discussed are provided. (JN)

Cyclic voltammetry is a simple experiment that has become popular in chemical research because it can provide useful information about redox reactions in a form which is easily obtained and interpreted. Discusses principles of the method and illustrates its use in the study of four electrode reactions. (Author/JN)

Using ascorbic acid enzyme assays in conjunction with chronoamperometric measurements, reliable values for the principal electroactive components in the rat caudate extracellular fluid were established. Techniques used in the study are discussed. (JN)

The use of the word "fact" in science is discussed. It is suggested that the everyday meaning of the term is assumed when it is used in science and that this can create problems. Some possible ways of overcoming these difficulties are indicated. (Author)

Describes an interactive computer program designed to provide graphical representations of chemistry and engineering experimental data sets and results of data analyses. Extremely flexible, the program requires no reprograming when new models are used. Models are entered into the program as input lines. (JN)

Describes Loyola University chemistry faculty training program. Areas addressed during the program include admissions (tests and test interpretation, financial aids, student selection), academic/psychological/moral student counseling, professional relations, curriculum/instruction (planning, strategies, teaching aids, grading), and professional…

Learning cycles (exploration, invention, application) are used to introduce general chemistry principles while giving students concrete experiences with descriptive chemistry. Principles taught in the laboratory, laboratory experiments, instructional strategies, and evaluation of the approach are discussed. (Author/JN)

Examines the basking postures of captive eastern painted turtles exposed to two different sources of illumination (white floor lamps and infrared heat lamps) and three types of substrates (sphagnum, rock, wood) and discusses possible ecological and evolutionary significance of these behaviors.
