Suggests an organizational plan for the reading resource room that would provide more sustained interaction between teacher and students than commonly occurs and that would allow optimal use of materials. (DD)

A mathematics laboratory is described that plays a central role in an undergraduate and graduate teacher education program. The laboratory allows students to relate mathematics content with teaching methodology and instructional planning systems. (MP)

A discussion of the basic design and characteristics of gas chromatography-mass spectrometry systems used in clinical chemistry. A comparison of three specific systems: the Vitek Olfax IIA, Hewlett-Packard HP5992, and Du Pont DP-102 are included. (BB)

Describes and evaluates the Tel-X-Ometer, its performance, and its accessories. The apparatus, with its low intensity x-ray beam, is specifically designed to make x-ray experiments safe, practical, and affordable for the students. (GA)

Describes procedures that students can follow to develop latent prints. An introduction of chemistry of latent prints is also presented. (HM)

Describes the use of ethyl or methyl ethanoate mixed with trichloromethane to illustrate intermolecular forces and deviations from Raoult's Law. (MLH)

Describes an undergraduate experiment in which Gantrez AN polymer chains are crosslinked at the anhydride groups by the addition of the hydroxyl groups of triethanolamine, which also acts as a basic catalyst. (MLH)

Describes an experiment in which metal compounds, such as anhydrous oxides, are placed into a glass tube which is heated until the metal colors the glass. (MLH)

Discusses the preparation of a solution of assigned molarity as a suitable test of laboratory technique for nonscience majors. (MLH)

Describes how to build and calibrate an apparatus utilizing modern circuitry that quickly and accurately measures dipole moments. (MLH)

Describes a study of the kinetics of the recombination of nitrogen atoms in which concentration-time relations are determined directly by utilizing visual observations of emissions to make gas phase titrations of N atoms with NO. (MLH)

Lists materials and methods for an experiment that demonstrates the concept of glomerular filtration rate (GFR) using anesthesized dogs. In the dog, GFR is equivalent to the renal plasma clearance of exogenous creatinine. (CS)

Describes an experiment using rats that demonstrates contractile characteristics of normal and hypertrophied muscle. Compensatory hypertrophy of the plantaris muscle is induced by surgical removal of the synergistic gastrocnemium muscle. Includes methods for determination of contractile properties of normal and hypertrophied muscle and…

A heat reclaim system and careful insulating will cut energy use in a University of North Carolina, Chapel Hill, medical laboratory-office building. (Author/MLF)

Describes a physical chemistry experiment that uses dynamic nuclear magnetic resonance spectroscopy to determine the barrier to rotation in N,N-dimethylacetamide by measuring changes in line shapes as a function of temperature. (MLH)
