Describes a carefully integrated presentation of visuals, demonstrations, stage magic, and music used to familiarize laypersons as well as students with the applications and fascination of modern chemistry. Suggests that this approach can be used by others for classroom and/or public-oriented ventures. (JN)

Background information (including chemical reactions) and procedures used are provided for (1) three buffer demonstrations and (2) a demonstration of phase transfer catalysis and carbanion formation. (JN)

The use of sodium acetate solution to show supersaturation is a favorite among lecture demonstrations. However, careful adjustment of the solute-to-water ratio must be made to attain the most spectacular effect--complete solidification of the solution. Procedures to accomplish this are provided and discussed. (JN)

Describes two demonstrations that require almost no preparation time, are visually stimulating, and present a variety of material for class discussion (with sample questions provided). The first involves a sodium bicarbonate hydrochloric acid volcano; the second involves a dissolving polystyrene cup. Procedures used and information on…

Describes a simple apparatus used to demonstrate the thermal conductivity of gases. Procedures for completing the demonstration are included. (JN)

Describes six demonstrations used in a medical biochemistry course. These demonstrations focus on: (1) platelet aggregometry; (2) ion-transporting antibiotics; (3) glycosylated hemoglobin; (4) molecular models; (5) serum preparation; and (6) bioluminescence. (JN)

Procedures for two demonstrations are presented. The first is a demonstration of chemiluminescence. The second is a demonstration using a secondary battery constructed from common household articles. (JN)

Describes an experiment on Doppler effects using air cars on a linear air track and a homodyne Doppler radar system. (SL)

Students in hydrogeology classes commonly have difficulty appreciating differences between the mechanisms of water release from confined and unconfined aquifers. Describes a simple and inexpensive laboratory model for demonstrating the hydraulic responses of confined and unconfined aquifers to pumping. Includes a worked example to demonstrate the…

This article describes how a gas chromatograph may be used to determine the amount of carbon dioxide in exhaled air. The experiment has been used as part of a demonstration exercise at a local science fair and proved of interest to all age groups. (Author/BB)

"Bench Remarks" is a new series dealing with chemical transformations of descriptive chemistry. The series begins with brief descriptions of several experiments with flames in an article titled "Flames: A Demonstration Lecture for Young Students and General Audiences" by Henry A. Bent. (JN)

List of materials needed, procedures used, and results obtained are provided for two demonstrations. The first is an inexpensive and quick method for demonstrating column chromatography of plant pigments of spinach extract. The second is a demonstration of cathodic protection by impressed current. (JN)

Background information, procedures, and typical results obtained are provided for two demonstrations. The first involves the colorful complexes of copper(II). The second involves reverse-phase separation of Food, Drug, and Cosmetic (FD & C) dyes using a solvent gradient. (JN)

The use of a logarithmic amplifier preceding an oscilloscope's vertical amplifier is described for physics teachers who want to demonstrate the exponential decay nature of some phenomena. (Author/SA)

A chemical demonstration book project was described. (BB)
