An apparatus is described for storing laboratory glassware in freshman organic chemistry laboratories. The glassware is mounted on pegboard using hardware gripper clips, and the pegboard is fitted in a slot down one side of the storage cupboard. (BB)

Presents a simulation model approach to the study of evolution. This model combines both practical and theoretical aspects of evolutionary biology course work. The author has used laboratory hardware for this simulation with 20 working groups of students. (HM)

Described is the construction and use of an environmental garden. The garden serves as a source of both indoor and outdoor laboratory materials, including vascular plants, fungi, algae, mosses, zooplankton, and macroscopic invertebrates. (BB)

This experiment uses the effect of the relativistic mass increase of electrons on the results of x-ray photoelectron spectrometry to obtain the rest energy of electrons. (BB)

This symposium centered on the choice of content in chemistry courses. (BB)

A chemical demonstration book project was described. (BB)

Presented here are improvements in the original design of an introductory statistical thermodynamics experiment with the result that heat capacities of metals are routinely obtained within ten percent of literature values. (BB)

In this paper an experiment is described in which the equilibrium constants necessary for determining the composition and distribution of lead (II)-oxalate species may be measured by linear sweep voltammetry. (Author/BB)

This experiment develops the students' ability to carry out a simple recrystallization effectively, and demonstrates how a solvent may be selected or rejected for the recrystallization of a specific organic compound. (Author/BB)

The setup described here for recording chemical transient phenomena is intended to be simple and an instructive example of interfacing experiments that can be performed on any microcomputer possessing adequate memory and input-output facilities. (BB)

A practical exercise is described that allows students to investigate a specific problem using a variety of biochemical techniques. The need for a thorough understanding of the theoretical principles underlying these processes is emphasized. A program of private study and assessment is suggested to enable the progress of students to be followed.…

Describes an exercise that illustrates the synthesis of an amino acid and Michael type condensation. The exercise can be used with college students of chemistry or biochemistry. (HM)

This reaction is used in an introductory organic chemistry course to illustrate principles of gas-liquid chromatography, geometrical isomerism, homogeneous catalysis, and activation energy determinations. (BB)

Data reveal that the absorption spectra of alkali metals can be analyzed using a modified laboratory procedure. ( CP)

Tested demonstrations on (a) color development through the formation of subtractive primary dyes and (b) fluidity of gases are presented. (CP)
