The use of green metrics to compare three bromination laboratory procedures demonstrates the effectiveness of an incremental greening process for chemistry curricula. Due to this process, the bromination of alkenes can be introduced to students through the use of a safe, effective, modern practice.

Examination of the Faraday constant is conducted using a speedy electrolysis experiment. This cost-effective, easy and fast procedure makes it highly suitable for classroom applications.

A series of sophisticated, combined laboratory experiments are developed involving the use of various spectroscopic and other techniques in the conformational analysis of cyclohexane mechanisms. The multi-system approach enables the students to transcend the one-dimensional procedure, and develops their synthetic and diagnostic skills.

The locust is well known for its ability to jump large distances to avoid predation. This class sets out a series of investigations into the mechanisms underlying the jump enabling students to bring together information from biomechanics, muscle physiology, and anatomy. The nature of the investigation allows it to be undertaken at a number of…

Synthetic polymers are prepared and tested in a study for their molecular recognition properties of an adenine derivative, ethyl adenine-9-acetate (EA9A), within two laboratory periods. The procedure introduces undergraduate chemistry students to noncovalent molecular imprinting as well as the analytical techniques for assessing their recognition…

This study examined the hypothesis that the association between hostile attributions and aggressive behavior with peers is moderated by children's temperament among three samples of preschoolers. Hostile attributions were assessed through videotape-based and story-based laboratory procedures. Maternal ratings and laboratory-based assessment…

Core concepts can be integrated throughout lower-division science and engineering courses by using a series of related, cross-referenced laboratory experiments. Starting with butane combustion in chemistry, the authors expanded the underlying core concepts of energy transfer into laboratories designed for biology, physics, and engineering. This…

Functional brain imaging has overshadowed traditional lesion studies in becoming the dominant approach to the study of brain-behavior relationships. The proponents of functional imaging studies frequently argue that this approach provides an advantage over lesion studies by observing normal brain activity in vivo without the disruptive effects of…

The Bureau of Labor Statistics (United States Department of Labor, Bureau of Labor Statistics [BLS], n.d.) has shown that workers involved in accidents have little, if any, instruction on the equipment they were using while injured. Keep in mind that instruction on the safe operation of a piece of equipment may take place early in the school year,…

Discusses the code of the Royal Institute of Chemistry (RIC) in Great Britain concerning laboratory safety; includes sections on hazardous chemicals and techniques, and legal responsibilities. (MLH)

This document is the fourth supplement to a 1984 bibliography on laboratory animal welfare. Items presented were selected because they represent some of the most significant of those providing recent information or because they were considered useful. The period covered is October, 1986 through October, 1987. Monographs, conference proceedings,…

Described is an activity that was developed to measure celestial coordinates. Pictures were taken of the asteroid Vesta, coordinates for reference stars determined, and then celestial coordinates of Vesta were determined with assistance of a computer. (RH)
