Illustrates an interesting biomedical application of adsorption from solution and demonstrates some of the factors that influence the in vivo adsorption of drug molecules onto activated charcoal. Uses acetaminophen and N-acetylcysteine for the determination. Suggests several related experiments. (MVL)

Describes several experiments using the techniques of thermal analysis and thermometric titrimetry. Defines thermal analysis and several recent branches of the technique. Notes most of the experiments use simple equipment and standard laboratory techniques. (MVL)

Discusses a computer simulation to teach logic design using a Macintosh computer which allows circuits to be built piece by piece. Describes features of the simulation and presents several schematics drawn by the software. (MVL)

Discusses programs to provide a knowledge base and use the knowledge in a mode of artificial intelligence. Indicates that two methods of database storage are possible and opts to use a method using many data files while using a small RAM capacity. Lists several programs. (MVL)

Describes the methods and materials used to obtain satellite pictures from weather satellites. Discusses possible physics lessons which can be done using this equipment including orbital mechanics, and how the satellite works. (CW)

Discussed are some uses of computers in chemistry classrooms. Described are: (1) interactive chromatographic analysis software; (2) computer interface for a digital frequency-period-counter-ratio meter and analog interface based on a voltage-to-frequency converter; and (3) use of spectrometer/microcomputer arrangement for teaching atomic theory.…

An approach to teaching the properties of the elements and their arrangement in the periodic table is suggested. Discussed are symbols for the elements, format of the table, and coding the properties of the elements on the table. (CW)

A brief history of several of the early forms of the periodic table of the elements are discussed including those of Mendeleev, Meyer, Hubbard, Gmelin, Von Antropoff, and Strong. A more every-day-life form of the table is presented. (CW)

Discussed are general considerations for educating visually impaired students including planning, testing, lecture/discussion, field trips, and laboratory activities. Fourteen activities that have been adapted are described. One such undergraduate course is described. (CW)

Reviewed is a television-based course available on videotape, "The World of Chemistry," which includes 26 programs. Discussed are the content, the sponsorship of the program, format, availability, and reviewer comments. (CW)

The theory behind concept mapping and advance organizers is reviewed. Special variations of concept mapping are presented. Evaluation using concept maps and long-term retention are discussed. (CW)

Discussed are some of the ways that community colleges may assist school districts and individuals with inservice teacher education. A program at Valencia Community College (FL) is described. Cooperation between the public school and the college is stressed. (CW)

A review of some of the different forms that biological ethics have taken in the past and of issues which are arising suggests that ethics should be taught as a part of biological education within a framework of history, futures study, training in clear thinking, and the development of empathy. (Author/CW)

Instructions are given for constructing two models, one to illustrate the general principles of symmetry in T=1, T=3, and T=4 viruses, and the other to illustrate the disposition of protein subunits in the T=3 plant viruses and the picornaviruses. (Author/CW)

Described is a workstation equipped with a personal computer and a research-quality data-acquisition interface for instrumental data acquisition and analysis for chemistry and physics courses. Hardware, software, and functions of the apparatus are discussed. (CW)
