Describes programs that have been developed to allow kinetic experiments to be simulated on a small computer. Reports the principles that have guided the conception of the programs and describes an instance of their application to a complex reaction. (Author/GS)

Discusses the world's energy requirements in contrast with the world's known and unknown energy reserves to illustrate the need for a stable and more equitable world-wide energy distribution system, especially for oil-importing countries. (CC)

Reviews current research interests in photographic chemistry, involving two proposed models for spectral sensitization of crystal defects and impurities in the photolysis reactivity and the mechanisms of development and complexation. Establishment of photographic chemistry in a chemistry curriculum is recommended. (CC)

Discusses the use of a computer program to describe chemical reactions by the concepts of reaction coordinate and energy profile. Indicates that representation of a collision encounter by a trajectory on the energy surface leads to a precise explanation, rather than schematic, in the teaching chemical kinetics. (CC)

Describes the methods of individualized instruction and teaching by example as effective tools in chemistry courses to bring disadvantaged students up to an acceptable level of competence. (CC)

Discusses the use of simulation games and real-life "role models" to teach introductory chemistry to a class, mostly of biology and engineering majors. Included is a suggested time schedule for a role-playing exercise. (CC)

Contained are five questions related to chemistry and ecology. Satisfactory answers to these five questions are included. (RH)
