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)

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)

Describes the contents of a book entitled The Care and Feeding of Ideas: A Guide to Encouraging Creativity which considers the thinking process, why skills need to be developed, and how students use or should use these thinking skills. (RT)

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)

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 the work behind one successful popular science program which does not trivialize the image of science. Discusses areas including science and broadcasting, one of the longest running science and technology programs on television, the mass media and health, and media fellowships for scientists. (RT)

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)

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)

Described is a unit of study on nuclear weapons from a course on nuclear technology. Provided are the elements of first strike attack designed for invoking students' interest and an explanation of each. (YP)

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)

Develops a compact minicell design in which the measured voltage is close to the desired emf. Notes student's observations for several cells are within 0.02V of the expected values. Presents numerous reasons for using miniware and semimicro qualitative analysis. Full experimental writeup is available from the authors. (MVL)

A peer review process similar to that used by scientific journals which can be applied to class work is presented. Stressed is the advantage of using peer review when writing skills are a priority but instructor time is limited. Guidelines and examples of comments are provided. (CW)
