Describes four cases for which simulation techniques can be used to analyze the kinetics of the chemical system. Included are series first-order and enzyme kinetics. (MA)

Introduces an approach to teaching amino acids that employs the use of a poem containing information on the structure and properties of amino acids, and of slides illustrating the poem. Student response to the method was positive. (MA)

Data from this study suggest that evaluations of long-term accumulations of students' laboratory analyses should be standard procedure to detect deviations from the accepted true assays. Efforts are recommended to determine the cause of the error and the implications or grading procedures reconsidered. (Author/MA)

Compares four different scoring systems in a study of 103 subjects answering a 20 item multiple choice test. Three of the four systems uses a weighted response technique, giving credit for partial knowledge. This seemed to have a significant effect on final grades and gave a more accurate grade representation. (MA)

Describes the scientists and the work they did to study mechanisms of stable complexes of cobalt (III) using kinetic methods. Traces the work from 1946 to the present. (MA)

Describes two demonstration experiments for the chemistry laboratory: (1) Thermodynamic vs kinetic control and (2) Acid-Catalyzed Hydrolysis of Starch. (MA)

Describes a forensic science course designed to give criminal justice students the knowledge and technology of science to solve a crime. The article includes a listing of topic areas, suggestions for the presentation of the content material, and an outline of the content and design. (MA)

Discusses different foods with reference to oxidation and energy production. Amino acid assays are provided for eggs, steak, rice, and lentils and white and dark turkey meat is analyzed for energy and power outputs. (MA)

Presents several suggestions for improving technical writing skills from organization through revision. (MA)

Discusses ways of teaching the mole concept in high school chemistry classes. Provides resource information on the mole and Avogadro's Number. Includes an explanation of four methods for measuring Avogadro's Number and instructions on how to use the mole. (MA)

Reports the findings of a study done to compare student attitude and achievement in two different chemistry curriculum programs. Results indicate no significant difference in either attitude or achievement scores on the exam administered. Neither program was found to be better than the other. (MA)

Presents chemical information related to dental health: (1) the composition of toothpaste, (2) dental diseases, (3) the role of fluoride, (4) proper oral health care, (5) mouthwashes, and (6) adhesive sealants. (MA)

Describes procedures for the disposal of chemicals commonly used in secondary school chemistry laboratories. Special reference is given to inorganic salts. It is suggested that cyanides and other highly toxic salts should be disposed of by experts. (MA)

Compares the preparation and decomposition of potassium dibromoiodate and of phenyl iodine dichloride in a flexible experiment which accustoms the student to handle halogens, to test for halogens in mixtures, and to appreciate the difference between thermodynamic and kinetic control of reactions. (Author/MA)

Details a laboratory experiment designed to extend the calcium PVC matrix membrane ion-selective electrode studies to complex formation equilibria. (Author/MA)
