Discusses the growing field of cosmetic science as a career option for chemistry majors. Outlines the design, formulation, manufacture, stabilization, evaluation, control management, safety, mechanism of action, and claim substantiation of cosmetic products. Provides information on the concerns and professional responsibilities of the cosmetic…

Proposes that an undergraduate core curriculum minimizes science and does not provide students with an adequate background for understanding contemporary science and technology. Critiques Harvard's science requirements in that it does not reflect the vertical or intensive nature of learning that is essential in science education. (ML)

Reports on a study of position descriptions in the field of hydrogeology appearing in want ads, published studies describing the working professional, and published descriptions of hydrogeology programs. Results indicate an increase in positions of ten times that of five years ago. Suggests basic training requirements for beginning…

Suggests chemistry should be better taught to undergraduates with more emphasis on lifelong learning experience. Emphasizes the collaboration needed between chemistry disciplines. Lists suggestions for curriculum change in chemistry. (ML)

Surveys the types of computers being used in high school and university chemistry courses. Identifies types of hardware found on Apple and MS-DOS computers. Makes recommendations for the upgrading of current equipment. (ML)

Described are the energetics involved in the formation of molecular hydrogen using concepts that should be familiar to students beginning the study of molecular orbital theory. Emphasized are experimental data on ionization energies. Included are two-electron atomic and molecular systems. (CW)

Discusses how to interpret nuclear magnetic resonance (NMR) spectra and how to use them to determine molecular structures. This discussion is limited to spectra that are a result of observation of only the protons in a molecule. This type is called proton magnetic resonance (PMR) spectra. (CW)

Details two demonstrations for use with an overhead projector in a chemistry lecture. Includes "A Very Rapidly Growing Silicate Crystal" and "A Colorful Demonstration to Simulate Orbital Hybridization." The materials and directions for each demonstration are included as well as a brief explanation of the essential learning involved. (CW)

Explores how an existing program can be adapted for remote control. Compares the output on the screen of an Apple II computer with its equivalent on the braille display of the VersaBraille. Points out some of the advantages of using a data base as a customized information center. (CW)

In this article, part I of a series, the forensic methods used in "typing" human blood, which as physical evidence is often found in the dried state, are outlined. Background information about individualization, antibody typing, fresh blood, dried blood, and additional systems is provided. (CW)

Defines and discusses activated complexes, transition species, and reaction intermediates in composite reactions. Stresses the importance of the precise use of language in science. (CW)

Proposes a series of experiments that integrate analytical techniques in order that students are able to compare, based on their laboratory results, the relative reliabilities of the most common therapeutic drug monitoring methods. Discusses materials, procedures, and results of three experiments on the determination of drug concentration by…

Describes a simple, inexpensive experiment in which students determine the heats of combustion of common solid, liquid, and gaseous fuels. The experimental apparatus, procedures, calculations and results are discussed. (CW)

Uses simple models to illustrate the principles of this genetic method of mapping gene loci. Stresses that this system enables a practical approach to be used with students who experience difficulty in understanding the concepts involved. (CW)

Describes a simplified redox method for total iron analysis suitable for execution in a three-hour laboratory period by general chemistry students. Discusses materials, procedures, analyses, and student performance. (CW)
