Discusses the design of two experiments on the reactions of 1-Chloro-1, 2-diphenylethane and of C-5 halides with nucleophiles in an inservice teacher course. Indicates that the material can be applied in teaching chemistry at both secondary and college levels. (CC)

Describes an experiment which yields low-volatility phenylacetylene, and suggests the use of the liquid product to examine alkyne chemical reactivity in organic chemistry courses. (CC)

Describes a variety of experiments that can be performed using the disposable syringe. Among others, these include the removal of oxygen during rusting, convection in a liquid and in air, gas collection in an electrolysis cell, small scale production of a fog, and hydrogen/oxygen extraction from a voltameter. (JR)

Results of on-site inspections of 11 New York colleges, laboratories and storage facilities are summarized according to: (1) chemical storage and disposal; (2) safety equipment; (3) ventilation; (4) general housekeeping; and (5) safety education. (Author/SK)

Discusses how the concept of organoleptic chemistry permeates every modern chemical experiment. Six approaches for developing organoleptic attitudes which are crucial to the experimental aspects are also presented. (HM)

Described is a procedure for the study of condensation polymerisation. The objectives of this study are to help students understand concepts that are somewhat abstract in nature (i.e., polymerisation) through derivation of equations that help to describe and predict the particular phenomena. (CS)

Describes a straightforward vertical fall experiment using a badminton shuttlecock, a tape measure, and a millisecond timer. The effects of air resistance are important and directly measurable. The experimental data best fit a predictive model which assumes a resistive force quadratic in the instantaneous speed of the falling object. (GS)

Presents an experiment involving photochemical legand displacement on a metal carbonyl, separation of the product mixture by chromotography, and identification of the components by use of infrared spectroscopy and group theory. The chromatography and spectroscopy are combined as complementary tools in this experiment. (Author/JN)

Describes a method to detect the presence of microgram quantities of nearly any metal in samples of alloys, minerals, water, and air. This chemical-spot testing technique requires no elaborate equipment and can be done by an amateur. (SK)

The use of pesticides in the schools is discussed. Some potential hazards include seeds dressed with fungicide/insecticide mixtures, fumigation of animal houses and greenhouses, and storage and disposal of pesticides. (SA)

Describes laboratory experiments of a chemistry course on advanced process control. The equipment for the process around which these experiments were developed by the University of Louisville was constructed from data provided by Exxon Oil Company. (HM)

The results of testing a theoretical model for laboratory psychomotor skill development are described. Research implications for fine motor learning in the chemistry laboratory are given. (Author/SA)

This paper, presented at the conference on the role of the laboratory in physics education which was held in Oxford, England in July 1978, describes how a Malaysian University has presented electronics and the laboratory work as a forced component in physics curriculum. (HM)

A description of an apparatus for demonstrating the trajectory of a charged particle, is given. A photograph of the equipment used in the demonstrations accompanies the text. (SA)

This experiment is intended as a classroom demonstration. It describes the preparation of materials, the procedure, and a few remarks related to demonstrating travelling waves of chemical activity in the Zaikin-Zhabotinskii-Winfree Reagent. (SA)
