Describes experiments which could be performed on an 1860 rotating table apparatus. (CP)

Describes an undergraduate kinetics experiment, including advantages of this particular system, sources of error, and expected results. (MLH)

Discusses the laboratory use of a titration end-point detection that relies on a temperature change rather than a color change. (MLH)

Describes a physics experiment for medical students to demonstrate equilibrium of the lower arm. (GA)

This method uses the cathodic deposition of silver from a cyanide solution in a non-partition cell with stainless steel electrodes. (BB)

This article describes the design, preparation, and initial evaluation of a set of computer-simulated chemistry experiments. The experiments entailed the use of an atomic emission spectroscope and a single-beam visible absorption spectrophometer. (Author/IRT)

Describes some of the scientific experiments of Joseph Henry, his role as a scientist and an educator, his contributions to physics teaching both at the precollege and college levels. (GA)

The method involves the dissolution of a small piece of metallic lithium in a small quantity of tertiary alcohol followed by addition to a mixture of the isocyanate and the tertiary alcohol in ether. This should be useful in organic chemistry laboratory courses for the identification of tertiary alcohols. (Author/BB)

The preparation of "p"-carboxystyrene from carboxybenzyl bromide in aqueous media is described. This is an example of a Wittig procedure that can be performed by students in one afternoon. (BB)

The Meerwein reaction is often omitted from undergraduate organic chemistry laboratory books. This experiment, the preparation of "o"-chlorocinnamic acid from "o"-chloroanaline, illustrates this section. (BB)

This safe and efficient procedure for the synthesis of N-substituted amides and hydrazides is a modification of the Schotten-Bausmann procedure in which the amine or hydrazide is replaced by the corresponding hydrochloride salt, and the use of alkali is eliminated. (Author/BB)

Human visual recognition on the basis of shape but regardless of size was investigated by reaction time methods. Results suggested two processes of size scaling: mental-image transformation and perceptual-scale transformation. Image transformation accounted for matching performance based on visual short-term memory, whereas scale transformation…

In this review of Gamberg's book, the differences in educational philosophy between China and Canada are brought out, emphasizing the ways in which inculcation of competitiveness and individualism in Canada promotes capitalism while inculcation of cooperation in China promotes a different set of values. (Author/MC)

Describes a laboratory procedure to obtain nuclear magnetic resonance (NMR) values for common organic and inorganic groups. (CP)

Includes eleven short notes, comments and responses to comments on a variety of topics such as uncertainty in a least-squares fit, display of diffraction patterns, the dark night sky paradox, error in the dynamics of deformable bodies and relative velocities and the runner. (GA)
