Presents a method for demonstrating Seebeck, Peltier, and Thomson effects in a single experiment. (SL)

Contains contributed suggestions for laboratory equipment, chemistry activities, and explanations of chemical reactions. (CP)

Describes a soap film demonstration apparatus. Presents information on the construction of the apparatus and methods for thin-film demonstrations. (YP)

Discusses theory of thermodynamics of the equilibrium in solution and dissociation-dimerization kinetics. Describes experimental procedure including determination of molar absorptivity and equilibrium constant, reaction enthalpy, and kinetics of the dissociation-dimerization reaction. (JM)

Describes two quantitatively-oriented physiology laboratories for veterinary students. The laboratory exercises incorporate the procedures of radiology and physical examination with measurement of pulmonary function. Specific laboratory objectives, procedures and equipment needed for diagnoses of the pathologies are listed. (ML)

Describes procedures for disposing of dichromate cleaning solution, picric acid, organic azides, oxalic acid, chemical spills, and hydroperoxides in ethers and alkenes. These methods have been tested under laboratory conditions and are specific for individual chemicals rather than for groups of chemicals. (JN)

Identifies the characteristics and components of a quality laboratory program for secondary science students. Suggests approaches, questions, and activities that aim to provide challenging experiences in the sciences. Also provides a listing of recommended laboratory standards and procedures. (ML)

As part of a project focusing on techniques in industrial chemistry, students carry out experiments on separating copper from cobalt in chloride-containing aqueous solution by liquid extraction with triisoctylamine solvent and search the literature on the separation process of these metals. These experiments and the literature research are…

Describes a Grignard reaction in a step synthesis that can be used in the laboratory to demonstrate several experimental and instrumental techniques. (MLH)

Describes an experiment that follows the progress of a chemical reaction with radiochemical tracer techniques, using the beta-emitting radioisotope iodine 131. (MLH)

Describes the construction of an amplifier and force transducer that can be used to demonstrate electrical activity in nerve and muscle using the gastrocnemius muscle and sciatic nerve of the frog. (MLH)

Described are filming of laboratory activities in 14 classes to determine class movement time, pupil centered activity time, and teacher centered activity time. Proportions of times ranged as follows: movement, 4-21 percent; pupil centered, 29-85 percent; teacher centered, 11-64 percent. (SL)

Discusses the philosophy and organization of an introductory college physics course that emphasizes laboratory experiments. Also presents a brief outline of the laboratory work. (MLH)

Describes an introductory laboratory physics course covering dynamics, fields, and waves. The course involves six hourrs of laboratory work and six hours of self-study every two weeks. Understanding concepts rather than laboratory techniques is stressed. (MLH)

Describes a laboratory teaching technique in which a single topic (in this case, bipolar junction transistors) is studied over a period of weeks under the supervision of one staff member, who also designs the laboratory work. (MLH)
