Teratogens are agents which act during pregnancy producing physical/functional defects in the embryo, fetus, or offspring. Discusses teratogenic hazards in the workplace and academic environment, classes of teratogenic compounds, precautions for interpreting Teratogen List from Registry of Toxic Effects of Chemical Substances (RTECS), and how…

Describes Loyola University chemistry faculty training program. Areas addressed during the program include admissions (tests and test interpretation, financial aids, student selection), academic/psychological/moral student counseling, professional relations, curriculum/instruction (planning, strategies, teaching aids, grading), and professional…

A cooperative lab program between local high schools and the University of Utah was initiated in 1975. Describes reasons for university's interest in such a program, guidelines high school teachers have agreed to follow, and program requirements/operation. Includes student/teacher comments on the program. (Author/JN)

After introducing the scientific method, nonscience students are given a two-part assignment: writing a research proposal and conducting the proposed research. Eight examples of student research projects are provided, including general comments about and student evaluations of the research project assignment. (JN)

Questionnaires were sent to 120 colleges/universities in the Mid-Atlantic Region (MAR) to obtain information on contemporary approaches to teaching biochemistry lecture/laboratory courses. Highlights of the survey are reported, focusing on library holdings, textbooks/laboratory manuals used, laboratory equipment used, and course length. (Author/JN)

Ten computer programs (available from authors) and a noncomputer calculation of the electron in one-dimensional, one-Bohr box are described, including programs for analytical chemistry, space group generation using Pascal, mass-spectral search system (Applesoft), microcomputer-simulated liquid chromatography, voltammetry/amperometric titrations,…

A laboratory computer system based on the Commodore PET 2001 is described including three applications for the undergraduate analytical chemistry laboratory: (1) recording a UV-visible absorption spectrum; (2) recording and use of calibration curves; and (3) recording potentiometric data. Lists of data acquisition programs described are available…

Describes fluorescence demonstrations related to several aspects of molecular theory and quantitized energy levels. Demonstrations use fluorescent chemical solutions having luminescence properties spanning the visible spectrum. Also describes a demonstration of spontaneous combustion of familiar substances in chlorine. (JN)

Student involvement in 24 science classes (grades 8, 9, 10) during instruction involving teacher exposition, exposition with prop, and demonstration was videotaped. Findings indicated that only nine teachers used class demonstrations and that the increased levels of pupil attention and task involvement increased during demonstration lesson…

Describes a course designed to provide secondary school science teachers with the background necessary to implement an effective safety program for their science labs. Lectures, demonstrations, group discussions, slides, films, videotapes, and guest speakers were utilized in the two-credit hour, summer course. Evaluations indicated course…

Learning cycles (exploration, invention, application) are used to introduce general chemistry principles while giving students concrete experiences with descriptive chemistry. Principles taught in the laboratory, laboratory experiments, instructional strategies, and evaluation of the approach are discussed. (Author/JN)

Describes a set of undergraduate laboratory experiments which provide experience in deuteration and derivatization procedures applied to infrared spectroscopy. Basic skills in vacuum-line technique are also taught while measuring infrared spectra of deuterated solid samples and demonstrating the value of derivatization as an aid to interpreting…

Highlights procedures and results of an experiment using atomic absorption spectroscope to illustrate a fundamental chemical concept. The experiment demonstrates the dependence of the solubility product of lead sulfate on ionic strength in the presence of a slight excess of anion. (Author/JN)

Describes a two-quarter hour college chemistry course focusing on laboratory safety. Includes lists of topics/assignments, problem sets (toxicology, storage, and energy) and videotapes, films, and slide sets used in the course. (JN)

Potential-pH diagrams show the domains of redoxpotential and pH in which major species are most stable. Constructing such diagrams provides students with opportunities to decide what species must be considered, search literature for equilibrium constants and free energies of formation, and practice in using the Nernst equation.
