Lists 12 science-oriented computer programs (indicating program name, source, RAM needed, compatible computers, and current cost). Also considers the use of these programs in educational and home settings. (JN)

Describes a series of challenges related to areas other than the knowledge content of a course to achieve a similar goal. These challenges are designed to teach not only analytical skills but also such process skills as organization, record keeping, report writing, cooperation with fellow workers, and resolution of discrepancies. (JN)

Presents biology, chemistry, physics, and health activities, experiments, demonstrations, and computer programs. Includes mechanism of stomatal opening, using aquatic plants to help demonstrate chemical buffering, microbial activity/contamination in milk samples, computer computation of fitness scores, reservoir project, complexes of transition…

Provides directions for setup and performance of two demonstrations. The first demonstrates the principles of Raoult's Law; using a simple apparatus designed to measure vapor pressure. The second illustrates the energy available from alcohol combustion (includes safety precautions) using an alcohol-fueled missile. (JM)

Describes a comprehensive nuclear magnetic resonance (NMR) experiment designed to introduce undergraduate organic chemistry students to measurement/interpretation of NMR parameters. Students investigate chemical shift analysis, spin-spin coupling, peak integrations, effect of deuterium oxide extraction, and comparisons with literature spectra;…

The sea urchin provides an ideal embryology laboratory because it is visually representative of the fertilization process in higher animals. Procedures for conducting such a laboratory (including methods for securing specimens) are provided. (JN)

Introduces a procedure for a whole class of experiments which require very simple and inexpensive equipment and which illustrate one of the basic problems of chemical reaction engineering. The reactions are designed to allow development of a kinetic rate equation from laboratory data. (JM)

Describes a class project in which students determine the best brand of paper towel in several categories. The activities and experiments completed during the project foster observation, measuring, collecting, data evaluation, writing, and mathematics skills. (BC)

Describes the procedures and equipment for an experiment on the adiabatic expansion of gases suitable for demonstration and discussion in the physical chemical laboratory. The expansion produced shows how the process can change temperature and still return to a different location on an isotherm. (JN)

Describes a new method and apparatus (consisting of a steel sheet, electromagnet, base, balls, and carbon paper) used to perform mechanics experiments which, until now, required use of an air table. Also compares the apparatus to an air table, explores its range of uses, and examines rotational dynamics. (DH)

Describes a series of short-term modular experiments which focus on community structure (standing crop biomass) and function (system energy flow). One exercise examines decomposers while another shows energy use by individuals. Equipment needed, procedures used, and results obtained are included. (Author/DH)

Materials needed and procedures for conducting two activities are provided. The first investigates drops of a liquid which float on water in a watchglass resting on top of a loudspeaker. The second investigates electromagnetic phenomena. (JN)

Describes (in the form of a hypothetical discussion between teacher and student) several demonstrations using the fine-beam cathode-ray tube. One is a demonstration of how a magnetic field can help to initiate and propagate a fine beam. (JN)

Provides a collection of data on the mechanistic aspects of inorganic chemical reactions. Wherever possible includes procedures for classroom demonstration or student project work. The material covered includes gas phase reactions, reactions in solution, mechanisms of electron transfer, the reaction between iron III and iodine, and hydrolysis. (GS)
