Reviewed are the features of lasers that make them useful to chemists and in chemistry curricula. Types of lasers are listed. Laser-induced fluorescence experiments are discussed. (CW)

Described is a chemistry program for high school students in rural Pennsylvania administered by Juniata College. Support, programing, equipment, and management of this van-based program are discussed. The positive effects on the students, teachers, and the college community are stressed. (CW)

Describes an aircart upon which a person can sit. Discusses the construction and use of it in a physics class. (YP)

Discusses a group project for a physics laboratory using various pendulums. Presents diagrams of pendulums, describes how to make a pendulum, and provides suggestions for guiding students in the laboratory. (YP)

Describes three experiments with an air table to produce a centripetal force. Provides some diagrams and pictures of the apparatus. (YP)

Discusses the general construction of an air track. Describes three demonstrations including elastic collision, forced oscillators, and coupled oscillators. Provides a diagram and four pictures. Suggests how a similar exhibit could be constructed with a modest budget. (YP)

Described are two investigations carried out in a high school biology department using a domestic microwave oven to compare the relative attributes of the autoclave and microwave oven in school use. Discussed are equipment, methods, and results of each investigation. (Author/CW)

Introduced are two experiments: radon detection method shows real data using vacuum cleaner, soft toilet paper, and Geiger-Muller tube; critical potentials measurement describes the operation of Teltron tube with VELA. (YP)

Describes the New Jersey Chemistry Olympics involving events such as library research, laboratory experimentation, model building, and computer programing. The goals, operational plan, competition events, and evaluation of the Olympics are discussed. (YP)

Discusses a tutorial slide package for oscilloscope operation. Provides source address and price for obtaining it. (YP)

Introduces an experiment involving the observation of Brownian motion for college students. Describes the apparatus, experimental procedures, data analysis and results, and error analysis. Lists experimental techniques used in the experiment. Provides a circuit diagram, typical data, and graphs. (YP)

Describes the Packard's Falling Body Apparatus, invented by John C. Packard, which is essentially an inclined plane combined with a simple and elegant method of measuring the relative time of descent of a steel ball. (JRH)

Described are activities that allow students to identify stars, planets, nebulae, and another galaxy. Practical preparations for the field trip are included as well as directions for observing the moon, looking at constellations, measuring the sky, plotting the paths of shooting stars, and planet spotting.
