Reports on the 9th Biennial Conference on Chemical Education sponsored by the American Chemical Society. The conference theme: "Chemistry: Learning, Instructing, Presenting," was addressed by numerous sessions. Highlighted were presentations calling for an increase in process-oriented chemistry teaching, reduction of "science…

Describes a laboratory safety program at the University of Delaware. Includes a history of the program's development, along with standard safety training and inspections now being implemented. Outlines a two-day laboratory safety course given to all graduate students and staff in chemical engineering. (TW)

Describes an experiment which uses the Gran plot for analyzing free ions as well as those involved in an equilibrium. Discusses the benefits of using Gran plots in the study of acids, as well as other analytes in solutions. Presents background theory along with a description of the experimental procedures. (TW)

Describes a two-week concentrated laboratory course in chemistry offered by Union College (New York) for middle school students. Provides the objectives of the course and a listing of experiments done by the students. Promotes the use of experiential approaches rather than lengthy lectures and discussions. (TW)

Presents two models and two demonstrations targeted at student understanding of projectile motion as the sum of two independent, perpendicular vectors. Describes materials required, construction, and procedures used. Includes a discussion of teaching points appropriate to each demonstration or model. (JM)

Presents chemistry experiments, laboratory procedures, demonstrations, teaching suggestions, and classroom materials/activities. These include: game for teaching ionic formulas; method for balancing equations; description of useful redox series; computer programs (with listings) for water electrolysis simulation and for determining chemical…

Outlines a variety of laboratory procedures, classroom materials, and demonstrations including a demonstration of the Markownikoff rule; blue bottle reaction and photosynthesis; a cheaper version of Fehling's solution; chemical formulas for younger students; chemical bonding and periodicity cards; optical activity demonstrations; and six others.…

Reviewed are two computer software packages the "Scientific Routines Diskette: Laboratory Automation Using the IBM PC" and "SEQS 3.0 Student Version Simultaneous Equation Solver" for IBM and compatible personal computers. Discussed are hardware, components, level, cost, functions, strengths, and weaknesses. (CW)

Three activities--"Earth's Orbit and the Four Seasons,""Observing Rabbits," and "Solutes, Solvents, and Solutions"--are described. Included in each are background information, a list of materials, key questions, teacher preparation, teacher introduction, procedure, and follow-up activities. (CW)

The use of electronic mail in the science classroom is discussed. Several applications of the use of this technology in the science classroom are described. Optional activities on computer networks are suggested. (CW)

Describes a problem-solving activity integrating a laboratory investigation with a database activity using Appleworks. Presents typical displays of the databases. The objective of the laboratory was to determine the identity of a pure substance by measuring physical properties and searching the database. (Author/YP)

Presented is a science activity designed to help students monitor the pH of rainfall. Materials, procedures and follow-up activities are listed. A list of domestic and foreign sources of information is provided. Topics which relate to acid precipitation are outlined. (CW)

Described are two methods which use microcomputers to illustrate the use of the electrocardiogram and the function of the heart. Included are a simulation and a method of collecting live electrocardiograms. Hardware, software, and the use of these systems are discussed. (CW)

Provided is an empirical method to train students to avoid physical disaster in their work experience. Discussed is a computer program, CHETAH, which can be used in advance of synthesis to classify the possible explosive nature of the products. Plosophoric and auxoplosive weights of many organic groups are listed. (MVL)
