Describes an experiment designed to give accurate values for both the absolute zero of temperature and the gas constant using very simple apparatus. (TW)

Provides a listing of 35 demonstrations designed to generate interest in organic chemistry and help put points across. Topics include opening lecture; molecular structure and properties; halogenation; nucleophilic substitution, alkenes and dienes, stereochemistry, spectroscopy, alcohols and phenols, aldehydes and ketones; carboxylic acids, amines,…

Describes use of computer simulation which generates bird songs so that students can analyze song motifs and sequences as an introduction to descriptive analysis of behavior in an animal behavior course. Advantages of the simulation are discussed together with computer hardware/software needed and data presentation, analysis, and generation…

A study comparing the use of the Silent Way technique in an experimental setting with its use in a real classroom setting suggests that results of experimental research cannot necessarily be transferred directly to the classroom. Student compositions based on ten Silent Way worksheets and an editing task are appended. (MSE)

Describes a self-demonstration experiment designed to teach the principles of the spark-ignition system. (SB)

Part of a project--Gothenburg, Teaching Methods in English--conducted at the University of Gothenburg and the Gothenburg School of Education in Sweden. (DD)

After providing information on elementary schooling in Yugoslavia, discusses ecological topics and activities used to raise the awareness of elementary school students about the level of pollution in the environment and the dangers of an increasingly polluted environment. Students' keen interest in chemistry and the chemical experiments was noted.…

The carabid beetle (Notiophilus) preys readily on an easily-cultured collembolan in simple experimental conditions. Some features of this predator-prey system are outlined to emphasize its use in biology instruction. Experiments with another potential collembolan are described in the context of developing the method for more advanced studies.…

This article focuses on the discussion of teaching chemistry to the handicapped and particular techniques that are useful to the communication process. (SA)

Describes three accessories developed to be used in conjunction with the rotating platform or turntable. Three demonstrations using these accessories are included. These demonstrations are: (a) conservation of angular momentum; (b) gravity-defying goblets; and (c) direct measurement of centripetal force. (HM)

Presents two methods for measuring the index of refraction of glass or lucite. These two methods, used in the freshman laboratory, are based on the fact that a ray of light inside a block will be refracted parallel to the surface. (HM)

Presents nine selected chemistry notes which could be used in school chemistry courses. Each includes the name of the author, a description of activities suggested and a list of references. (HM)
