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)

This article presents a vector-analysis approach to the classical three-point problem in hydrogeology. Problem sets involving strike and dip, and ground water flow including computer programs (in BASIC) for their solution are given. (CW)

An interactive videodisk entitled "Motion: A Visual Database" developed at the Cambridgeshire College of Arts and Technology (CCAT) is described. Three of its 194 real experiments are discussed. (YP)

The results of surveys of biology staff and students at Scottish universities concerning attitudes to the use of animals in education are reported. Discussed are survey methods used, the results of each survey, and bioethics in general. The staff and student questionnaires are both included. (CW)

Describes making laboratory apparatus such as a heavy-duty turntable; a hand-held milk-carton accelerometer; an inverted air table; free-fall measurement with a solenoid as a starting device; and a bright point source. Presents an evaluation of "The Champ Universal Interface and Sensor Pack Software." (YP)
