Provides a summary of the events occurring at the Ninth Biennial Conference on Chemical Education, held in Bozeman, Montana, on July 27-August 2, 1986. Contains brief descriptions of sessions on the role of chemists, demonstrations of laboratory experiences, learning chemistry with computers, teacher training, and chemistry for elementary school…

Free radical chlorination of methane is used in organic chemistry to introduce free radical/chain reactions. In spite of its common occurrence, demonstrations of the reaction are uncommon. Therefore, such a demonstration is provided, including background information, preparation of reactants/reaction vessel, introduction of reactants, irradiation,…

Describes the history, chemistry, and uses of sulfuric acid. Presents demonstrations with this the cheapest bulk acid that is available in every country of the world. (PR)

The success of teaching molecular and atomic phenomena depends on the didactical strategy and the media selection adopted, in consideration of the level of abstraction of the subject to be taught and the students' capability to deal with abstract operations. Dale's cone of experience was employed to plan three 50-minute classes to discuss protein…

Describes a method for adapting Piagetian theory to the teaching of chemistry by increasing active student thinking in lectures. Laboratory demonstrations are supported as encouraging Piagetian self-regulations. (CS)

Describes a high school chemistry experiment which involves the reaction between calcite and hydrochloric and sulfuric acids. This reaction can be carried out as a projected demonstration and on an individual basis. (HM)

Presents laser demonstrations of the surface photoelectric effect and the measurement of the laser beam wavelength; recommended for teaching the relationship between light energy and wavelength. (MLH)

Discusses some interesting kitchen chemistry experiments. Describes the use of baking aerators and baking powders in an inexpensive experiment. Outlines several demonstrations to follow up the experiment and to illustrate other chemical principles. (TW)

Describes a simple way to demonstrate the principles involved in a drinking water plant. This demonstration developed for a general public lecture can be used in chemistry and biology courses for an ecological and environmental emphasis. (HM)

Describes 13 activities, experiments and demonstrations, including the preparation of iron (III) chloride, simple alpha-helix model, investigating camping gas, redox reactions of some organic compounds, a liquid crystal thermometer, and the oxidation number concept in organic chemistry. (JN)

Advocates motivating chemistry students while maintaining high academic standards. The curriculum, materials, and motivation techniques used are discussed. The latter includes presenting magic shows to elementary students, decorating rooms, celebrating chemists' birthdays, performing unusual/exciting demonstrations, and others. (JM)

Described are demonstrations provided for secondary school students designed to illustrate the fun and wonder of chemistry and learning by experimentation. A list of the contents for the videotapes and suggestions for discussions using the videotapes are provided. (CW)

Describes and discusses the procedure for a demonstration, found in the CHEMStudy film "Shapes and Polarities of Molecules" and in the Nuffield Advanced Chemistry and Physical Science materials, to qualitatively illustrate the differences between polar and non-polar liquids. (PEB)

Presented are three demonstrations: "The Construction and Use of Commercial Voltaic Cell Displays in Freshman Chemistry"; Dramatizing Isotopes: Deuterated Ice Cubes Sink"; and "A Simple Apparatus to Demonstrate Differing Gas Diffusion Rates (Graham's Law)." Materials, procedures, and safety considerations are discussed. (CW)

Advocates using classic lectures in chemistry as guidelines for good teaching. Uses quotes from an 1848 book of lectures by John Scoffern to illustrate teaching principles relating to teacher enthusiasm, relevant materials, simple demonstrations, good laboratory experiences, nomenclature, and practical applications.
