Combines coordinate systems, planetary positions, use of the celestial globe, and synodic period in a graphing exercise. Information is given to duplicate an occurrence of 1940 in which five naked eye planets were simultaneously visible. (CP)

Presents five demonstrations for use in chemistry classes. Materials needed, procedures, and explanations are included. (RH)

Describes medieval alchemical experiments that can be reenacted in the undergraduate laboratory. (MLH)

Describes a biochemistry experiment involving the kinetics of passive diffusion of solutes across artificial membranes formed by dispersing phospholipids in aqueous medium. (MLH)

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)
