The study presents and explains the various periodicity symbols, tables and models for the higher-order valency and donor-acceptor kinships used in chemistry. The described alternative tables are expected to improve the pedagogical consistency of the chemical periodicity patterns with better electronic behavior.

Describes modifications included in an examination procedure allowing students to take an exam on a given unit twice, and the use of nonobjective exams. The grading of exams by the professor in consultation with the student was viewed as the most productive aspect of the course. (GS)

Explains the benefits of physical exercises to the human body, pointing out that inactivity is the major contributor to the lack of physical fitness in America. Concludes that sugar, which has no nutritional value, is very harmful to the body. (GA)

A discussion of problems students have with the concept of percent, with special emphasis on the use of percent in elementary chemistry. (BB)

Discusses different foods with reference to oxidation and energy production. Amino acid assays are provided for eggs, steak, rice, and lentils and white and dark turkey meat is analyzed for energy and power outputs. (MA)

Compares the metabolism in muscles of athletes with the energy usage patterns of the United States and India. (BB)

The work output of a human body in various tasks and the biochemistry of oxygen consumption in muscles is discussed. (CP)

Calculates energy expenditures for the activities of running and bicycling and discusses the heat dissipative perspiration system of the human body. (CP)

Proposes that including historical perspectives in chemistry instruction to aid in building a historical perspective of the interplay in science of facts, logic, and ideas. (SL)

Illustrates the frustrating search for the best way to teach college chemistry, by pointing out that there are problems associated with any type of curriculum, teaching technique, or grading method. Includes statistics on a Keller type physical chemistry course. (MLH)

This paper, presented at the McMaster International Conference on New Directions in the Chemistry Curriculum, discusses the answers to five questions which deal with basic philosophy concerning new chemistry curricula. (HM)

Discusses similarities between chemistry and three central concepts of quantum physics: (1) stationary states; (2) wave functions; and (3) complementarity. Based on these and other similarities, it is indicated that quantum physics is a chemical physics. (JN)

Discusses combustion by suggesting several experiments and demonstrations using matches. Integrates quotes from famous scientists about the various phenomenon regarding combustion. (TW)

Presents evidence to support the author's viewpoint that Einstein's General Relativity Theory is related to concepts of chemo-electricity. (CS)

Presents dialogs between selected humanists and a thermodynamicist adapted from the author's NSF-AAAS Chautauqua-type short course on "Thermodynamics, Art, Poetry, and the Environment." (CS)
