Describes safety practices for laboratory fume hoods based on certain assumptions of hood design and performance. Also discusses the procedures in preparing to work at a hood. A checklist of good hood practices is included. (JM)

Provides information based on explorations of the Apollo program about the geochemistry of the moon and its importance in developing an understanding of formation/evolution of the solar system. Includes description and some results of orbital remote sensing, lunar x-ray experiments, gamma-ray experiments, alpha-particle experiments, and the Apollo…

Describes an advanced, senior-level biochemistry course designed for students planning to pursue careers in nursing, engineering, and agriculture. The course follows a college-type format to expose students to college level course work. Course description, outline, and supplementary materials are included. (JM)

Factors affecting traditional laboratory instruction in chemistry are discussed. They include: responses to potential hazards in the undergraduate laboratory; student distaste for laboratory classes; equipment and chemical costs; lack of qualified teaching assistants; and faculty pressures to do research. New directions for introductory…

Describes a fourth-grade unit on density which introduces a concept useful in the study of chemistry and procedures appropriate to the chemistry laboratory. The hands-on activities, which use simple equipment and household substances, are at the level of thinking Piaget describes as concrete operational. (BC)

Determined if differences in performance on a posttest (in which sections differed in use of manipulative models to answer questions) were attributable to differences in reasoning levels of chemistry students (N=105). Results indicate that reasoning may affect performance under conditions of constant instruction. (JN)

Describes the development of the Nuffield chemistry curriculum materials by chemistry teachers and how these materials were received and used by a much larger and representative group of the profession. Includes comments on teaching Nuffield chemistry, the Nuffield examination, and on Nuffield chemistry outside of Great Britain. (JN)

Discusses Lehigh University's industry-funded centers and institutes, academic research projects designed to upgrade both industry and the economy, and research and development programs. Includes information on sources of research and development funding. (JN)

Describes an American Chemical Society (ACS) service which helps individuals not familiar with the resources of safety information. The service, which provides referrals to literature, films, educational courses, or organizations that can provide answers, exists to help in complying with legislation and dealing with all aspects of chemical health…

This paper illustrates the educational uses of the Word Wide Web in a university situation; it gives an account some of the ways in which the World Wide Web and other information technologies have been used to extend the scope of the history of science generally and the history of chemistry in particular. I observed that the World Wide Web…

In times when human beings used to live in a natural environment, their needs were also provided for by natural resources. With the increase in population over time, human beings started to look for new resources willing to get "the most" and "the fastest". Just like the invention of steam, first, they increased the density of the resources and…

This book is designed for middle school students to learn scientific literacy through event-based science. Unlike traditional curricula, the event-based earth science module is a student-centered, interdisciplinary, inquiry-oriented program that emphasizes cooperative learning, teamwork, independent research, hands-on investigations, and…

This book is designed for middle school life science or physical science teachers to help their students learn scientific literacy through event-based science. Unlike traditional curricula, the event-based earth science module is a student-centered, interdisciplinary, inquiry-oriented program that emphasizes cooperative learning, teamwork,…

Identifying the benefit of teaching chemistry through history was the goal of this study that used a quasi-experimental design based on the method of action research. Two groups of students in the last 2 years of a teacher preparation program participated in the study with one group receiving instruction on how to develop and teach chemistry…
