Some simple undergraduate laboratory experiments are described, which verify the energy-momentum relationship of special relativity. These experiments have been designed either to be used as classroom demonstrations or to be carried out by second-year students. (Author/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)

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)

Describes three accessories developed to be used in conjunction with the rotating platform or turntable. Three demonstrations using these accessories are included. These demonstrations are: (a) conservation of angular momentum; (b) gravity-defying goblets; and (c) direct measurement of centripetal force. (HM)

Presents two methods for measuring the index of refraction of glass or lucite. These two methods, used in the freshman laboratory, are based on the fact that a ray of light inside a block will be refracted parallel to the surface. (HM)

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)

Ideas intended for use in a high school biology laboratory are given. Swordtail fish are described as subjects for observation in animal behavior studies. (SA)

A programed, two-credit hour, experimental microbiology course for nonscience majors is described. (SA)

This experiment is suitable for an integrated laboratory course for senior chemistry majors. It introduces the student to a study of the relative basicity of different proton accepting sites. It serves as an opportunity to learn about nmr techniques and could extend to infrared, as well. (BB)

Describes an inexpensive technique for providing student opportunities to observe and identify the variety of small animals living in the first few inches below the surface of the soil. A classification key to some small soil animals is also presented. (HM)

Presents a series of behavioral objectives for a 60 hour science unit designed to train laboratory technicians in safety, basic laboratory skills, laboratory service and fittings, and first aid. (SL)

Presents two articles: "Modular Flexibility in an Individualized Introductory Cultural Anthropology Course," by Daniel D. Whitney and Patrick J. Dubbs, and, "Physical Anthropology as a Laboratory Science Course in a Community College," by Yechiel M. Lehavy. The former describes an individualized approach to anthropology, whereas the latter…

Describes a laboratory experiment for secondary school chemistry students utilizing the classic reaction between the iron(III) ion and the thiocyanate ion. The experiment also works very well in other chemistry courses as an experience in spectrophotometric analysis. (PVD)
