A systems thinking approach to incorporating green chemistry and safety into laboratory culture is vital, as chemists will be at the molecular level of the innovative solutions to our global challenges. Training chemists to have the skills and culture to accomplish this feat in the safest way possible is pivotal to safe working conditions within…

Argues that using outdoor classrooms to examine environmental studies will help heighten the student's awareness of the importance of protecting our environment. Describes how such a land laboratory could be developed. (RKM)

Although a complete oxygen meter is an expensive piece of equipment, homemade circuitry can be a suitable substitute if science teachers are aware of the limitations of the apparatus as well as of certain techniques for effective use. (PB)

Discusses the language laboratory as a means of developing practical abilities in a foreign language. Two topics are treated specifically: (1) the laboratory from a technical and theoretical perspective, and (2) an analysis of the language skills most effectively trained through use of the language laboratory. (AMH)

Presented is a short discussion of factors causing color changes in animals. Also described is an activity which may be used to demonstrate the response of amphibian skin to a melanophore stimulating hormone in high school or college biology classes. (PEB)

Answering critics of language laboratory effectiveness, this article presents a methodology for laboratory work which includes working in partnership. Necessary technical equipment is described. Learning goals are proposed, and possible further developments in the method are suggested. (IFS/WGA)

Described is the design of a low maintenance, foreign language laboratory at Ithaca College, New York, that provides visual and audio instruction, flexibility for testing, and greater student involvement in the lessons. (Author/CS)

Presents descriptions of three experimental procedures for physics classes: forced oscillations, measuring the refractive index of perspex, and measuring the critical potentials of helium. (SA)

Reported is a method of producing artificial lightning in an ordinary clear lightbulb. The appearance of sparks produced is that of a miniature stroke of forked lightning seen in natural thunderstorms. The sparks also show the intricate branching patterns often seen in natural lightning. (JT)

Compares various nutrient media, growth conditions, and stock solutions used in culturing protozoa. A hay infusion in Chalkey's solution maintained at a stable temperature is recommended for producing the most dense and diverse cultures. (WB)

Discusses the making of a light engine powered by sunlight or a lamp. Describes the materials and construction method with detailed specifications and diagrams. (YP)

An upper-level undergraduate experiment that, in addition to introducing students to catalysis using an air sensitive transition-metal complex, introduces the use of a solid acid as an activator and support for the catalyst is developed. The increased stability acquired in the course of the process affords the opportunity to characterize the…

The author discusses the method of preparing a television set or a projector to enable students in all parts of the classroom to see what is on the teacher's computer screen. By using this equipment, teachers can help students see the steps they must do. (CH)

Addresses bloodborne pathogen hazards in the laboratory. Provides specific recommendations for preventative measures and information about legal issues involved. (MM)

Lists 46 household chemicals readily available at local stores by common name, chemical name, chemical formula, and typical commercial source. Suggests that school budgetary constraints can be eased by this practice and that students can become more chemically literate as consumers. (JJK)
