Provided is a biographical sketch of Percy L. Julian (1898- ), an American Black organic chemist who first synthesized cortisone, testosterone, progesterone, and physostigmine. (CS)

Highlighted are characteristics of programs written for a pocket-sized programmable calculator to analyze mass spectra data (such as displaying high resolution masses for formulas, predicting whether formulas are stable molecules or molecular ions, determining formulas by isotopic abundance measurement) in a laboratory or classroom. (CS)

Describes construction of two inexpensive three-dimensional models (tetrahedrons) using glass tubing and colored plastic sheeting. Diagrams show how these models are used in explaining how a point is plotted in a four-component system and how the composition of a point is deduced from its position in the model. (CS)

Discusses a one-semester course offered in the School of Chemical Sciences at the University of Illinois at Urbana which incorporates technical writing and the use of the chemical literature into a single course. (CS)

Describes a physical chemistry experiment that allows students to test the effect of ionic strength on the rates of a reaction between ions. The reduction of hexacyanoferrate III by ascorbic acid is detailed. Comparisons with the iodine clock reaction are made. (CS)

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

Discusses safety in school laboratories and school lab accidents in Britain and suggests ways of reducing potential hazards of school science. (HM)

Assesses an evaluation model, employing an objectives rating system and a two-dimensional matrix to display the ratings, which was applied to 145 behavioral course objectives for a general chemistry course at Northern Virginia Community College to judge the appropriateness and adequacy of the course objectives. (AYC)

Presents information on the Georgia Institute of Technology. This information includes: (1) a brief history of the institute; (2) names of the faculty members of the chemistry and metallurgy divisions; (3) undergraduate program; and (4) graduate program. (HM)

Presented are the results of a survey conducted to identify occupational health efforts in university chemistry laboratories. (HM)

Describes the development and operation of a mastery learning scheme used with part-time students in an HNC chemistry course. (Author/GA)

Describes how social aspects of science can be incorporated into teaching soap and detergents in British secondary chemistry and general science courses. Historical background to the use and production of soap and the development of detergents are also presented. (HM)

Describes some chemical aspects of the operation and use of the internal combustion engine and some developments in their historical and social contexts in the United Kingdom. (HM)

The new chemistry facility at the University of Akron, heralded as one of the safest chemistry buildings ever constructed, is described. Topics discussed include: preliminary planning, general building design, design of specific areas, and safety training for personnel. (BT)

Describes an attempt to develop and staff a new first-year laboratory course at the University of Jordan. A postgraduate course in chemical education is used as the development and training vehicle. (BT)
