Describes a new, modified "flash chromatography" apparatus which overcomes difficulties found in conventional apparatus. For example, an expensive teflon pressure valve is not necessary in the modified version. The apparatus is suitable as an instructional tool in undergraduate courses. (JN)

Background, procedures, and results are provided for an experiment which examines, through electron spin resonance spectroscopy, complex species formed by cupric and 2,6-dihydroxybenzoate ions in aqueous solutions. The experiment is illustrative of several aspects of inorganic and coordination chemistry, including the identification of species…

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…

Describes a simple and effective method in which students use their hands, arms, and fingers to determine absolute configurations. (JN)

Presents an overview of the glass-to-rubber transition, what it is, why it is important, and the major factors that influence it. Indicates that this information should be incorporated into chemistry curricula. (JN)

Describes an interdisciplinary, college-level course on the chemical and physiological properties of selected drugs and medications. The course, which could be adapted for secondary school use, assumes no prior chemical or biological knowledge. Source materials, films used, credit/grading policies, instructional strategies, and course outline are…

Suggests that the new context for school science focuses on the real world, real people, and real issues. Areas considered include current problems in science education, the need for a new context, recommendations for a K-12 science curriculum, the science/technology/society (STS) movement, and STS curricula and programs. (JN)

Discusses the relationship of Karl Popper's theories to chemistry, examining scientific statements and verisimilitude (which indicates that newer theories should have a higher degree of truth content compared with older theories). Also provides examples illustrating the use of Agassi's criteria for assessing currently fashionable theories. (JN)

Examines various trends and issues in educational computing. Areas addressed include hardware advances, personal databases, laboratory data handling, graphic displays, national networking (including access of Project SERAPHIM materials through the CompuServe Information Service), software advances, Project SERAPHIM activities, and future…

Presented are flow charts to help students interpret infrared and nuclear magnetic resonance spectra of simple organic compounds. Advantages in using these charts are outlined. (JN)

Describes an approach which provides a basis for developing skills in interpreting infrared spectra and gives students a methodology which is functional without having to match "problem" spectra with "published" spectra. In addition, the suggested approach is reinforced easily by laboratory exercises involving known or unknown compounds. (JN)

An experiment which introduces students to infrared spectroscopy and the solubility behavior of various organic compounds is described. The experiment also serves to integrate some of the basic chemical reactions of functional groups with their spectral properties. (JN)

Offers suggestions and strategies related to integrating an instrumental approach in high school chemistry. Indicates that the problem-solving process is often clarified using the approach, that the approach improves the quality of the laboratory program, and that it is an effective technique for arousing student interest. (JN)

Procedures for two demonstrations are presented. The first is a demonstration of chemiluminescence. The second is a demonstration using a secondary battery constructed from common household articles. (JN)

Describes chemistry courses offered as part of a residential summer enrichment program held at the University of Northern Colorado. A list of elementary and advanced chemistry activities completed during the courses is included. (JN)
