This experiment is designed specifically for students with little knowledge of radical reactions and provides an introduction to the gas-phase chemistry of radicals. Experimental planning based on the student's own observation is an important component of the experiment. (Author/MA)

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)

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)

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 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 undergraduate experiment which will permit students to analyze the rotational Raman spectra of hydrogen and carbon dioxide and determine the bond distances. (SL)

Describes an experiment for determining the amount of BHA in cooking oil in an undergraduate level chemical technology program. (SL)

Describes an experiment for studying the dynamics of a soft spring. (SL)

Describes three experiments for undergraduates which illustrate associations of parasites with their host. Includes a table of parasite-induced alterations of selected host species. Instructional suggestions are also provided. (ML)

Describes a laboratory experiment which focuses on the importance of water in germination and seedling emergence. Discusses the activity's design, expected results, and possible application. Offers suggestions for extending the experiment. (ML)
