Discusses the photochromic behavior of mercury(II) bis(dithizonate) in providing a colorful demonstration of the effect that visible light can have on the conformation and bonding of molecules in solution. Provides a description of the demonstration itself, along with the preparation needed to complete it. (TW)

Provides a running commentary on a chemistry instructor's first day in a first course in chemistry. Focuses on the use of fire and chemists' attempts to explain this phenomenon. Provides the ongoing descriptions of the experiments, a summary of the observations, and the key comments made by the instructor. (TW)

Recounts the experiences of a student with cerebral palsy in a college-level, first-semester chemistry laboratory course. Explains how a laboratory assistant worked with the handicapped student in assembling apparatus and manipulating some of the smaller equipment. Discusses the outstanding work performed by the student. (TW)

Dicusses the use of the separatory cylinder in student laboratory experiments for investigating equilibrium distribution of a solute between immiscible phases. Describes the procedures for four sets of experiments of this nature. Lists of materials needed and quantities of reagents are provided. (TW)

Describes two examples where synthetic salt-base mixtures are used in a microscale organic laboratory program as a simple and quick procedure for carrying out Wittig reactions. Both experimental procedures are outlined and discussed. (TW)

Asks engineering graduates 15 questions to help them evaluate their potential for a management career. Explains the relevance of each question. Discusses self improvement strategies. Suggests some job search strategies for graduating engineers. (CW)

Describes the environmental programs that evolved out of the school of Public and Environmental Affairs at Indiana University. Discusses the organization of the school, the teaching approaches, research activities, the internship program, enrollment, and placement for students at both the undergraduate and graduate levels. (TW)

Describes the organization of a graduate course dealing with mass transfer, particularly as it relates to chemical reactions. Discusses the course outline, including mathematics models of mass transfer, enhancement of mass transfer rates by homogeneous chemical reaction, and gas-liquid systems with chemical reaction. (TW)

Describes an experiment developed and used in the unit operations laboratory course at the University of Wyoming. Involves the liquid-phase adsorption of an organic compound from aqueous solution on activated carbon, and is relevant to adsorption processes in general. (TW)

Describes a heat capacity experiment designed to provide an interactive environment between the student, the experiment, and the computer. Discusses computer software that has been developed so that the entire interaction can be coordinated from the computer keyboard. (TW)

Offers suggestions to advisers of undergraduate students in agriculture. Recommends that advisers be competent, concerned, compassionate, and provide an open-door attitude toward their advisees. Suggests that students be guided toward good study habits and participation in intern programs. (TW)

Summarizes the report of a National Research Council committee. Reports on three basic findings: the proportion of foreign born engineers in the United States has increased over the last 15 years; the increase is disproportionate in the academic sector; and large numbers of students are culturally different. (CW)

Describes a senior level chemical engineering course at Purdue University that parallels an industrial process development department. Stresses the course organization, manager-engineer contract, evaluation of students, course evaluation, and gives examples of course improvements made during the course. (CW)

Surveys British people over age 15 with the purpose of assessing the level of scientific knowledge among the public. Discusses the relationships between highest level of formal education, sex, and the answers given to questions. Illustrates how little school science instruction is remembered into adulthood. (CW)

Advances four propositions in an effort to provide a frame of reference for a new generation of interactive engineering graphics scholars. Suggests the integration of traditional engineering graphics with new production tools such as computer-aided design drafting. Proposes that graphics problem-solving educational opportunities be maximized. (CW)
