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)

Presents part two on the use of the detection of thermoluminescence as an analytical tool for the chemistry laboratory and allied science. This part discusses instrumentation used and investigates recent developments in instrumentation for thermoluminescence. (HM)

Discusses the cognitive outcomes of physics laboratory exercises and suggests three types of experiments which should be added to those normally used in physics courses. (HM)

Describes a physics laboratory for college students, in which the students participate in a firsthand noninertial experience. The equipment and problems are described. (SA)

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

Catalysis is defined and discussed as the process relates to science history, chemical reactions, enzymes, industry, catalytic reactors, and catalyst preparation. (SA)

A device is described to assist in designing prototype interfaces between a minicomputer and an external device. This device is especially useful in undergraduate student projects, where time is limited. (BB)

The contract learning laboratory program utilized during the 1974-75 academic year is described, including specially-designed experiments and typical results. A student evaluation of the program is also given. (LBH)

Discusses the importance of laboratory safety in science classrooms. Urges middle school teachers to address class size in an effort to establish and maintain a safe working environment. Answers a teacher's question related to having newts and salamanders in the classroom. (SOE)

Describes a sea-water analysis project that introduces qualitative and quantitative analysis methods and laboratory methods such as gravimetric analysis, potentiometric titration, ion-selective electrodes, and the use of calibration curves. Uses a problem-based cooperative teaching approach. (Contains 24 references.) (YDS)
