Describes a comprehensive nuclear magnetic resonance (NMR) experiment designed to introduce undergraduate organic chemistry students to measurement/interpretation of NMR parameters. Students investigate chemical shift analysis, spin-spin coupling, peak integrations, effect of deuterium oxide extraction, and comparisons with literature spectra;…

The sea urchin provides an ideal embryology laboratory because it is visually representative of the fertilization process in higher animals. Procedures for conducting such a laboratory (including methods for securing specimens) are provided. (JN)

Discusses methods for reducing or eliminating waste disposal problems in the chemistry laboratory, considering both economic and environmental aspects of the problems. Proposes inventory control, shared use, solvent recycling, zero effluent, and various means of disposing of chemicals. (JM)

Provides materials needed and procedures to illustrate the reversible color changes in certain organic acids on bases due to changes in pH. The technique employs three indicators which are colorless in acidic solution but form primary colors in basic solutions. Also discusses the free energy curve presented in many textbooks. (JM)

A science laboratory was developed for use by kindergarten through sixth-grade students. The operation of and the types of science activities used in this laboratory are described. (JN)

Microcomputer-based laboratories (MBLs) refer to a laboratory where a microcomputer gathers and displays data directly from the environment. Program listings for a response timer (using game paddles) to illustrate the nature of MBLs are presented. (JN)

Presents a table cross-referencing 12 physics laboratory manuals by topics. Topic areas include measurement and techniques, mechanics, molecular physics, waves and optics, electricity and magnetism, and quantum physics. (JN)

Techniques of classroom observation were used to increase teachers' awareness of the variable participation of boys and girls in science and craft lessons. The work indicates that considerable efforts may be needed to achieve the balanced participation of girls. (JOW)

A dental school's experience using data on student attitudes toward a restorative dentistry laboratory course and an experiment conducted during the course to make curricular and methodological changes, and subsequently evaluate those changes, is described. The questionnaire used and response tabulations are included. (MSE)

Provides a collection of data on the mechanistic aspects of inorganic chemical reactions. Wherever possible includes procedures for classroom demonstration or student project work. The material covered includes gas phase reactions, reactions in solution, mechanisms of electron transfer, the reaction between iron III and iodine, and hydrolysis. (GS)

Described is a method of converting vacuum-tube operated Heath analog computers (model ES-201) to linear integrated-circuits. (SL)

This article presents a practice theory for diagnosing organizations--that is, a combination of many ideas in a relatively simple framework that can be applied in various settings. It brings together organization/environment, sociotechnical, and formal/informal systems concepts, and proposes six broad categories for looking at an organization.…

Presents a series of discussions on the general elements of experimental design and the scientific process and relates these elements to the field of communication. (MH)

The Brooklyn Center branch of New York's Long Island University has an impact on the entire downtown of Brooklyn. The library serves the needs of the poor adjacent communities, of businesses in the downtown area, and of five nearby colleges. (Author/MLF)
