Lists and provides a few examples of computer-based studies appropriate for use in undergraduate physical chemistry. (CS)

Provides procedures, apparatus, and pre- and postlaboratory questions for an inexpensive, unsophosticated experiment that determines the approximate value for Avogadro's number. (CS)

Sixteen different suggestions are given to parents for helping their children with science fair projects. Among the 16 suggestions included are contacting people who have expertise in science, helping the child obtain pertinent information, keeping a daily log of research activities. (DS)

Described is an environmental awareness simulation game involving the life function of food getting. Instructions, charts, task sheets and questions are included for each segment of the game. (DS)

A science and social studies unit developed around rosin is described. Students develop an understanding of the processing of raw material from a plant source into a commercial product and how to protect wood from weathering by preparing, testing, and evaluating varnish and shellac for their wood protective qualities. (Author/DS)

Discusses distillation of liquid mixtures with the emphasis on experimental work. A number of experiments, intended for chemistry secondary school teachers in the United Kingdom, are included. (HM)

Presents a method for graphically illustrating Le Chatelier's principle, suitable for the general chemistry undergraduate. (CS)

Describes the philosophy of a high school chemistry teacher, providing examples through classroom experiences, with emphasis on the use of demonstrations as instructional aids. Specific stoichiometry and conductometric titration demonstrations are discussed. (CS)

Describes an experiment which makes use of a number of concepts from geometrical optics. The apparatus and method which is intended for students in elementary college physics classes are included. (HM)

Describes a modification in the use of artificial substrates to study attached micro-algae. Apparatus is based on glass microscope slides immersed in natural water environments; biomass and primary productivity are assessed by measurement of alpha-chlorophyll. Describes use in studies of colonization, succession, and populational fluctuation. (CS)

Describes an organic chemistry experiment demonstrating the effect of temperature on reactivity as measured by reverse phase high performance liquid chromatography. (CS)

Presents an undergraduate analytical chemistry experiment that promotes an interpretation of the molecular aspects of solute partitioning, enhancing student understanding of separation science and liquid chromatography. (CS)

Lists and describes a variety of major national astronomy organizations which amateurs can join. It also lists stores and institutions across the U.S. that offer a discount to members of the Astronomical Society of the Pacific (ASP). (Author/SA)

This article tries to provide both a justification for primary science and an introduction to the kind of science which can be fostered by nonspecialist class teachers in primary schools. (KC)

Described is a method for bringing the sea into the classroom by setting up a saltwater aquarium. Included is selection of an aquarium, filtering systems, water (whether natural salt or synthetic sea salts), bottom materials, setting up an aquarium, system stabilization, stocking an aquarium, and maintenance of the aquarium.
