Describes an apparatus for investigating the behavior of photoelectrons in a uniform magnetic field in either a vacuum or a low-pressure gas. Presents data and discusses some basic features of the photoelectric effect and the diffusion of free electrons in a gas. (GA)

This article describes two simple undergraduate heat transfer experiments which may reinforce a student's understanding of free convection and radiation. Apparatus, experimental procedure, typical results, and discussion are included. (Author/BB)

This article describes the undergraduate ChE thermodynamics course at Drexel University and the reasons for incorporating a series of laboratory experiments into the course. Included is a list of lecture topics and a description of each of the experiments. (BB)

Examines American and British policies concerning DNA research and gene transplantation. (CP)

Explains a laboratory experiment dealing with the optical features of the human eye. Shows how to measure the magnification of the retina and the refractive anomaly of the eye could be used to measure the refractive power of the observer's eye. (GA)

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)

Discusses Zeeman's experiment of the Fiyea effect for the speed of light in a moving medium and existing measurement errors. (SL)

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 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)

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)
