Discusses the importance of implementing new approaches in science teaching which will elevate citizen concerns to science-related issues confronting society. Outlines a biology application course designed to counteract current problems in this area. (RT)

Provides a listing of a software graphics program that investigates the law of reflection and Snell's law of refraction. Written in BASIC for the Apple II personal computer. (MVL)

Illustrates the basis for misleading statements about the relationship between pH and acid content in acid rain. Explains why pH cannot be used as a measure of acidity for rain or any other solution. Suggests that teachers present acidity and pH as two separate and distinct concepts. (RT)

Describes how the tapping of maple trees can be used to teach lessons in science on boiling points, density, solubility, and other sugaring projects in the curricula. Outlines activities and precautions to follow when doing this project. (RT)

Presents several fun activities and teacher demonstrations which simplify terms and condense science concepts for teaching about the lever, wedge, wheel and axle, screw, pulley, and the inclined plane. Includes objectives, materials, procedures, suggested follow-up assignments, and diagrams. (RT)

Asks the course planner, text writer, teacher, or even the student to consider a series of questions about Earth processes such as how, why, and where the process occurs and why is it important. Provides a guide for the coverage of a topic to ensure that nothing is overlooked. (Author/MVL)

Reports on the exchange of chemistry professors between the University of Wisconsin, Madison, and Oakwood College in Alabama. Explores the Madison Plan which has a long term goal of working toward educational excellence by taking advantage of the strengths inherent in ethnic diversity. (MVL)

Examined is the effectiveness of a smoking-prevention program in modifying high school students' attitudes and values in such categories as health, peer pressure, and social image as related to smoking. The intervention lasted four to six weeks within the framework of ninth- and tenth-grade biology classes. (Author/YP)

Describes a program which allows students to identify and characterize several kinetic inhibitory mechanisms. Uses the generic model of reversible inhibition of a monosubstrate enzyme but can be easily modified to run other models such as bisubstrate enzymes. Uses MS-DOS BASIC. (MVL)

This article reports on a study which investigated the question of whether the motivational and attitudinal components associated with wanting to do well, taking risks, and having a progressive ideology are empirically associated with staff ratings of quality. Subjects were 133 preservice primary teachers in England. (IAH)

Examines the thermal decomposition of sodium bicarbonate to sodium carbonate. Encourages students to predict the end products and to use the stoichiometric results to determine if their predictions are correct. (MVL)

Provides two demonstrations: (1) electrolyte migration of ions using colored ions which cross a strip of gelatin allowing for noticeable migration; and (2) photochemical reduction of Fe+3 by the citrate ion. Points out both reactions can be done in a Petri dish using common lab materials. (MVL)

States there is little direct evidence that the current laboratory instructional method is an important component of chemistry instruction. Provides a historical account of laboratory work. Studies individual work versus demonstrations, and computer simulations. Urges the use of computer based methods to provide a rich laboratory experience. (MVL)

Discusses several issues important to chemistry: enticing top-notch students into the discipline, keeping up with the tremendous growth of chemical information, and promoting chemistry to the general public. Suggests eight methods to answer these issues. (MVL)

Presents a method to teach stoichiometry where a problem is broken down into four factors and two cycles. Offers grams of known, moles of known, moles of unknown, and grams of unknown as the factors. Uses factor labeling as the second cycle. (MVL)
