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.…

Explains how the Mathcad computer program can promote the development of higher-order chemical thinking skills of students taking junior-level physical chemistry courses. The kinetics of first-order series and reversible reactions is used as an example of how this can be implemented within an interactive laboratory or lecture format. (PVD)

Describes the use of simple projects to help freshmen-level chemistry students develop chemical knowledge and an aptitude for the research process. These projects pose a new problem to students without presenting a detailed experimental procedure. Guiding questions help students design their own experiments and stimulate students to think…

Described is the status of science education reform in 1990. Different groups working on change, demographic trends in the US, student anecdotes, lab operations, the role of Sigma Xi, goals set by the state governors, industry efforts, and programs for the improvement of middle school teachers are discussed. (CW)

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)

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)

Provides a method to use superscripts and subscripts on the screen by using graphics screen modes. Gives two methods and provides a listing of a sample BASIC program. (MVL)

Examined student behaviors during laboratory activities and the amount of time involved in each behavior. Approximately 89 percent of the student time was spent interacting with others. The amount of time spent on various activities appeared to be dependent on the nature of the activity and on the make up of the laboratory group. (YP)

Presented is a review of a computer learning package "Lab Partner & Lab Master" for Apple II computers. Hardware requirements, components, functions, costs, and student reactions are discussed. Graphic analysis capabilities are stressed. (CW)

Eight articles are included in this collection. Topics include: multicultural science, teaching science with metaphors, development of a graded assessment scheme in science, relative performance of boys and girls in chemistry, promoting science understanding, formative evaluations, science background of primary teachers, and promoting creativity…

Surveyed 1200 students in a second semester general chemistry course at Purdue. Investigates areas where student and faculty perceptions of the content of chemistry courses differ. Elaborates on each area and suggests explanations for the findings involved. (MVL)

Discusses some of the contributing factors and chemical reactions involved in the production of acid rain, its effects, and political issues pertaining to who should pay for the clean up. Supplies questions for consideration and discussion. (RT)

Described is a course which combines the usual instruction in technical subjects of industrial chemical operations with some of the business aspects that compose the total commercial enterprise. The two-hour-a-week semester course syllabus is provided. A business game to develop a plan for business expansion is included. (MVL)

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)
