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)

Any overhead projector easily can be converted into a simple spectrometer by placing a piece of diffraction grating over the projecting lens. A detailed description of the apparatus and suggested spectroscopy experiments are included. Demonstrations can utilize solutions of cobalt chloride, potassium permanganate, potassium dichromate, or…

In this demonstration of the generation and combustion of acetylene, calcium carbide and water are allowed to react in a latex examination glove. Two student volunteers perform the demonstration with instructor guidance. This safe, popular demonstration, originally intended to illustrate the alkyne family of compounds, can be used with a variety…
