Discusses simulation program to aid in the design of enzyme kinetic experimentation (includes sample runs). Concentration versus time profiles of any subset or all nine states of reactions can be displayed with/without simulated instrumental noise, allowing the user to estimate the practicality of any proposed experiment given known instrument…

Eleven computer/calculator programs (most are available from authors) are described. Topics include visualizing molecular vibrations, dynamic nuclear magnetic resonance spectra of two-spin systems, programming utilities for Apple II Plus, gas chromatography simulation for TRS-80, infrared spectra analysis on a calculator, naming chemical…

Presents background information, laboratory procedures, classroom materials/activities, and experiments for chemistry. Topics include superheavy elements, polarizing power and chemistry of alkali metals, particulate carbon from combustion, tips for the chemistry laboratory, interesting/colorful experiments, behavior of bismuth (III) iodine, and…

Describes the life cycle, reproduction, and various classroom uses of the Louisiana Red Swamp Crayfish. Includes advantages and disadvantages of two different culturing techniques. (JN)

Describes an apparatus for plotting electric fields using burglar alarm window tape for electrodes and carbonized electronic stencil paper as sheet resistance. Also describes a simple pentode modulator circuit which will modulate a typical helium-neon gas laser, providing an audio channel for demonstration purposes. (SK)

Describes an experiment using chromatographic techniques on aging leaves which gives high school biology students the opportunity to observe, question, and formulate hypotheses. (CS)

Describes a method for undergraduate physiology students to measure plasma volume by the dye dilution technique, in which a computer is used to interpret data. Includes the computer program for the data analysis. (CS)

Procedures used by a primary science class to build five different working solar furnaces are summarized. Diagrams, illustrations, and graphs of children's results are included. (DC)

Laboratory procedures, equipment, teaching ideas, and resource materials related to physics are discussed. Topics include the construction of a liquid-metal pump, a hydraulic jack, and an apparatus which helps teach time/velocity graphs; current/voltage characteristics of a tungsten filament lamp; and an electric circuit game. (DC)

Presents chemistry activities suitable for elementary students. Lists chemicals commonly used in elementary science, their common names, and where they may be obtained. (DS)

Suggests individual student projects for extra-credit work to enhance student individuality. Provides a sample information sheet for independent projects (with suggested activities), a listing of project requirements, and a project evaluation checklist. (DS)

Describes the construction of an apparatus which can be used to demonstrate vapor pressures of solids, liquids, and solutions. (SK)

Describes the relationship of Popper's theory of knowledge to chemistry instruction. Suggests that students be allowed to learn from their mistakes and presents five experiments with an implicit falsification purpose. (JN)

Described are different chemistry curricula that use lecture-experiments. Different components are discussed within the lecture-experiment format, such as determinism, memory, note taking, descriptive chemistry, and holistic chemistry. Also discussed are different personalities in chemistry education. (DS)

Described is a diffusion apparatus to be used in an undergraduate physical chemistry laboratory experiment to determine the diffusion coefficients of aqueous solutions of sucrose and potassium dichromate. Included is the principle of the method, apparatus design and description, and experimental procedure. (Author/DS)
