Presents a quantitative laboratory experiment in geometrical optics. It involves the student in the measurement of the radius of curvature of the cornea and is based on an old method devised by Kohlrausch in 1839. (Author/GA)

Presents the results of two experiments concerning the phenomena of the interference of probabilities and of the so called Aharonov-Bohm effect. An electron biprism and a standard electron microscope have been used for the experiments. (Author/GA)

It is argued that there is a fundamental difference in the perception of the nature of man on the part of humanistic critics and traditional experimental social psychologists which leads to different assessments of the long-term effects of deception research on subjects. (Author/AM)

Presents an organic chemistry experiment consisting of a two step reaction sequence involving the Grignard synthesis of an alcohol followed by its oxidation to ketone. (SL)

Describes a physical chemistry experiment investigating the vapor-liquid equilibrium in a heterogeneous system. (SL)

Describes a nuclear magnetic resonance experimental example of spin tickling; also discusses a direct approach for verifying the relative signs of coupling constants in three-spin cyclopropyl systems. (SL)

Describes an experimental method of measuring the molecular weight and subunit corporation of an oligomeric protein. (SL)

Describes a procedure to demonstrate the effect of a magnetic force on a moving charge. The materials used are inexpensive and with the use of an overhead projector, easily visible to an entire class. (CP)

Describes a geology laboratory exercise involving weathering and topographic maps which allows students to put knowledge to practical application. (SL)

Describes a simple chemistry laboratory experiment which allows students to calculate thermodynamic values. (SL)

Describes a laboratory kinetic experiment which demonstrates the important phenomenon of general catalysis by bases and/or acids. (SL)

Examination of the snowfall and total precipitation data for Rochester, New York, suggests a correlation with sunspot activity. Data from other locations tend to support the thesis, but the ability to predict yearly snowfall or total precipitation amounts from sunspot activity has yet to be developed. (Author/CP)

Describes an experiment for determining the thermal neutron flux of the light-water nuclear reactor at the University of California, Irvine. The difficulty of the activity can be varied to match the student's level of proficiency. (SL)

Reports an undergraduate analytical chemistry experiment utilizing the high performance liquid chromatograph. (SL)

Describes an experiment investigating the polarization characteristics of light scattered from a dielectric cylinder. (SL)
