Proposed is an activity designed to teach the similarities and differences between artistic and scientific vision. Objectives, materials, procedures and follow-up activities are listed. Preliminary activities in physical science and earth science are suggested. (CW)

Activities that may take place in a greenhouse are discussed. Included are learning how to grow plants, plant growth, soil, vegetative reproduction, and plant habitat adaptations. Materials, procedures, and results are presented for the activities. (CW)

Described are two applications of computers in chemistry. The multilinear equations and procedures used in obtaining a least-squares solution for curve fitting in chemistry are presented. Also discussed is the program "ATORB" which can be used to generate graphs of probable electron clouds for various atoms and molecules. (CW)

Described is an introductory experiment that allows students to directly observe and measure the linear energy transfer in matter. Illustrated are the experimental setup including the radioactive source, electronic equipment, and the detector; measurement and calculations; and the results. (CW)

Provides reviews of courseware entitled: "Mystery Matter," which is a series that supplements the basic inquiry process; "Jumping Math Flash," which is an arcade-game program with arithmetic problems; and "Quest for Files: Science Rocks and Minerals The Upper Crust," which is a database program for earth science.…

Reviews the basis for the technique and its experimental requirements. Describes a few examples of the analytical problems to which surface-enhanced Raman spectroscopy (SERS) has been and can be applied. Provides a perspective on the current limitations and frontiers in developing SERS as an analytical technique. (MVL)

Presents the mechanistic ideas underlying reactions between nucleophiles and carbonyl compounds as well as some popular misconceptions. Relates reactions of carboxylic acid derivatives to those of aldehydes and ketones. Discusses leaving group ability and the ability of carbonyl oxygen to accept a negative charge. (Author/MVL)

Discusses ways people who live in rain forests make a living and some of the products that enrich our lives. Provides activities covering forest people, tropical treats, jungle in the pantry, treetop explorers, and three copyable pages to accompany activities. (Author/RT)

Notes the careful observation of chemical reactivity phenomena has been and should be an important part of the general chemistry laboratory curriculum. Stresses reduction of experimental scale will help to ensure, in times of rampant chemophobia, that it remains so. Provides several examples of the methodology. (MVL)

Reports the function of the Reactivity Network which is to translate reactivity data from the primary literature into some 30 reviews for high school teachers and curriculum developers and to disseminate that information nationwide. Discusses a needs assessment done for the project. (MVL)

Provides an eclectic annotated bibliography of secondary sources for inorganic reactivity information of interest to reactivity network review authors and to anyone seeking information about simple inorganic reactions in order to develop experiments and demonstrations. Gives 119 sources. (MVL)

Presents a halogen substitution of an alkane using a compartmentalized Petri dish or Conway dish on an overhead projector. Provides methodology and several modifications for different reactions. Uses hexane, methyl orange, bromine, and silver nitrate. (MVL)

Provides guidelines for a custom-made science program that integrates science, math, and technology. Describes the curriculum which is divided into themes including the applied sciences, cycles of the universe, plate tectonics, rock, water, and life. (Author/RT)

Reports on the evaluation of a district's science fair. Describes the procedure, literature and questionnaire findings, the effects of the study, and a summary. States that as a result, changes were made in the objectives, project awards, judging criteria, and guidelines for judges. (RT)

Explains a program specifically designed to help academically underprepared students who are seeking careers in health professions. Describes course content, traditional and nontraditional teaching methods used, and evaluation procedures. States that student performance significantly improved. (RT)
