Described is a physiological model which solves a set of interacting, possibly nonlinear, differential equations through numerical integration on a digital computer. Sample printouts are supplied and explained for effects on the components of a cardiovascular system when exercise, hemorrhage, and cardiac failure occur. (CS)

Details the possibilities for and the needs involved in the use of the language laboratory. Included are descriptions of the laboratory as a broadcast/library facility, as well as descriptions of the hardware and software involved. Hardware includes video, video disc, and computer systems. (PJM)

Presents three methods for removing silver nitrate stains, using (1) aqueous potassium iodide; (2) potassium ferricyanide in water; or (3) copper sulfate or chloride in water. (CS)

Presents two articles which are part of a series concerned with safety in school science in the United Kingdom. The two articles deal with restricted chemicals and experiments. (HM)

A listing of mathematics laboratory material is organized as follows: learning kits, tape programs, manipulative learning materials, publications, math games, math lab library, and an alphabetized listing of publishers and/or companies offering materials. (MP)

Presents background information, procedure, and results of an experiment, using easily obtainable chemicals and equipment, illustrating chemical kinetics. The experiment may be done in a letter as one four-hour physical chemistry laboratory period. (JN)

Presents a chemical instrumentation laboratory experiment that introduces the methodology of the fabrication and evaluation of an ion-selective electrode. (CS)

Presents methods by which undergraduate students gain practice in ESR spectroscopy. (CS)

Presented is an inspection form developed for use by college students to perform laboratory safety inspections. The form lists and classifies chemicals and is used to locate such physical facilities as: fume hoods, eye-wash fountains, deluge showers, and flammable storage cabinets. (BT)

From a safety point of view, there is a need to ensure that science teachers are appropriately qualified to teach their subject. Opportunities for accidents in school laboratories are legion and acquisition of skills and competence to obviate them is essential. (Author/RE)

Described is the design of a low maintenance, foreign language laboratory at Ithaca College, New York, that provides visual and audio instruction, flexibility for testing, and greater student involvement in the lessons. (Author/CS)

The experiment described is intended to illustrate the intermolecular phenomena involved in association colloids. These are normal and inverse micelles and lyotropic liquid crystals. Solubilization, microemulsion and emulsion are discussed. (Author/SA)

A device designed for sampling algae in rivers and streams is described. Techniques for observing algae in the laboratory as well as tips for maximizing success in sampling are given. (SA)

Explains two approaches to the automatic arrest of a potentiometric titration. (SA)

Presents descriptions of three experimental procedures for physics classes: forced oscillations, measuring the refractive index of perspex, and measuring the critical potentials of helium. (SA)
