Proposes the use of problems of the everyday world to motivate students to master basic physical principles. Cites the example of conversion of solar energy by a photovoltaic cell as a source of topics in electricity and solid state physics. (CP)

Gives highlights of two symposia on chemical education held in Madrid in September, 1975. Topics included the use of educational technology, teacher training, and curriculum. (MLH)

Describes an undergraduate chemistry experiment in which the concentration of chloride, fluoride, or bromide ions can be quantitatively determined by titrating with mercury (II) ions. (MLH)

Describes methods for teaching the mole concept, including analogous calculations involving household objects, and the use of a cardboard wheel showing the interrelationships between moles, molecular weight, and the gaseous molar volume. (MLH)

Describes a biochemistry laboratory course in which students worked in groups; each group selected three of nine possible experiments. Each student was responsible for using the chemical literature to obtain detailed procedures for performing the experiments, and submitted formal reports on each experiment. (MLH)

Describes an undergraduate organic chemistry experiment which illustrates the use of organoboranes in organic syntheses and provides for the anti-Markownikoff hydration of alkenes. (MLH)

Describes a circuit (utilizing simple equipment) which can be used to measure the period of a harmonic oscillator. (CP)

Offers a course description of an introductory course in physics for nonscientists. The history of research into extrasensory perception is used as evidence of the scientific method. Lecture demonstrations are discussed. (Author/CP)

Discusses an overall educational program to train both specialists and the public in food science. Presents food statistics, and discusses the importance of food engineering and applied microbiology courses. (MLH)

Applies the charge cloud model of atomic and molecular structure to three problems to show simplicity of calculations and interpretation of results. (CP)

Two mechanics problems which clearly show relativistic correction factors and may be suitable for introductory mechanics instruction are shown. (CP)

Describes a method to experimentally determine the longitudinal shift of a microwave beam at total internal reflection. Suggests that the activity be incorporated into an undergraduate laboratory program due to its ease in set-up and clarity of results. (CP)
