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)

Describes an experiment giving precise results of solubility as a thermodynamics property. (SL)

Describes an experiment studying the decay of moth balls to demonstrate diffusion phenomena. (SL)

Describes a freshman physics laboratory experiment for approximating the mean free path in high density gases by measuring the mean free path of hockey pucks on an air table. (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 a reaction system experiment utilizing saponification of ethyl acetate by sodium hydroxide. The activity is part of an undergraduate chemical engineering course. (SL)

Described is a laboratory exercise that uses nuclear magnetic resonance to monitor enantiomeric excess in asymmetric reductions. The laboratory exercise has been used successfully with undergraduate organic chemistry students. (RH)
