Reviews the history, nomenclature, theoretical background, and construction of batteries. Compares the performance of different battery types. (JN)

Investigates the effectiveness of a structured learning game in overcoming learning difficulties encountered by Israeli students when studying the life cycles of fungi because of lack of structural conceptualization. The Fungi Life Cycle Game (FLCG) was used by undergraduate students enrolled in a phytopathology course. (HM)

Reviews state-of-the-art of conformational analysis and factors which affect it. Emphasizes sp-3 hybridized acrylic molecules. Provides examples on the importance of certain factors in determining conformation. Purpose, is to provide examples for examination questions. (Author/SA)

Summarizes a theoretical approach using nonbonding MO's and perturbation theory to correlate properties of saturated hydrocarbons. Discussion is limited to correctly predicted using this method. Suggests calculations can be carried out quickly in organic chemistry. (Author/SA)

Describes a laboratory experiment which demonstrates manipulation of highly reactive chemicals, use of a gas trap, and simple and reduced pressure distillation. Student must characterize starting material and product with nuclear magnetic resonance and infrared spectroscopy. (Author/SA)

Presents information intended to encourage students to become thoughtful consumers. Discusses the role of pepsin in splitting off amino acids from stomach proteins and the nature of the protein substrate in determining the ph at which pepsin operates. Directions for an experiment are included. (Author/SA)

The study investigated specific student behavior in introductory and advanced college laboratories in botany, chemistry, geology, physics, and zoology. Behaviors were observed, described, and classified with no effort made to induce change, detail underlying conditions, or identify correlates. (Author/RE)

Discusses a method used at DePaul University of Chicago, Illinois, in a relativity course for students who are not science majors, emphasizing logical reasoning rather than memory of facts. (HM)

Discusses how the frequency domain (line widths) and time domain (coherent optical transients) are related to the concept of transverse relaxation time in the study of high resolution optical spectroscopy. (HM)

Presents the first of a series of articles that discuss the perception of sound and music. This series of articles is intended to provide an introduction to the broad subject of high-fidelity sound recording and reproduction. (HM)

Described are 22 computer programs, written in BASIC, currently being used by the Eastern Washington University Chemistry Department. Information on the availability of the programs from the author is provided. (BT)

Describes a method utilized at Iowa State University for teaching a biochemistry laboratory course for non-majors involving the use of student independent projects and experimental choices. (BT)

The role of technology throughout history and its relationship to science is discussed. The new frontier of societal technology is considered in terms of human behavior and misbehavior in the face of conflict. (SA)

The experiments described in this article discuss the versatility of the linear variation method in quantum chemistry and the ease with which it can be used with a simple computer program. (SA)

This is an experiment for college chemistry students in which they are introduced to gas phase and aerosal analysis and the chemical nature of cigarette smoke and its health hazards. (Author/SA)
