Science programs, such as the ones described in this publication, advance the goals of public library service to children. Throughout the programs, boys and girls are introduced to an array of literature exploring science topics. Librarians present subjects of great interest to children creatively using local experts, realia, child-conducted…

How do you get a fourth-grader excited about history? How do you even begin to persuade high school students that mathematical functions are relevant to their everyday lives? In this volume, practical questions that confront every classroom teacher are addressed using the latest exciting research on cognition, teaching, and learning. How Students…

Describes the equipment and laboratory procedures suitable for introducing junior high school students to the organic chemistry concepts involved in fractional distillation. (JR)

Discusses use of the VIC-20 microcomputers for laboratory interfacing. Topics considered include the game connections and use of: the ADC0809 A/D converter and timers with the VIC-20; the free-running mode of T1; and the pulse-counting mode of T2. Instructions and diagrams are provided. Descriptions of several programs are also provided. (JN)

Materials needed, reaction involved, and potential hazards are provided for a demonstration of reversible oxygenation. Also discusses the importance of the reaction in biological systems, focusing on hemoglobin/myoglobin and their function in mammals. (JM)

Preparation and testing of a cadmium selenide photoelectrical solar cell was introduced into an environmental chemistry course to illustrate solid state semiconductor and electrochemical principles. Background information, procedures, and results are provided for the experiment which can be accomplished in a three- to four-hour laboratory session…

Background information and procedures are provided for an experiment to prepare three metal derivatives of dimethyl sulfoxide (DMSO) and to determine some structural features of these derivatives based on their infrared spectra. Results and discussion of reactions involved are also provided. (JN)

Presents procedures, exercises, demonstrations, and information on a variety of biology topics including labeling systems, biological indicators of stream pollution, growth of lichens, reproductive capacity of bulbous buttercups, a straw balance to measure transpiration, interaction of fungi, osmosis, and nitrogen fixation and crop production. (DC)

Provides a prospective on electrosynthesis technology for chemical educators and students by discussing electrosynthesis reactions and experiments. Includes tables illustrating some electrochemical products, variables to consider in electrochemical reactions, indirect electrolysis of organic compounds, examples of direct/indirect electrochemical…

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…

An instrument for the continuous assessment of high school physics students' laboratory performance was developed and evaluated. Physics teachers (N=25) observed students conducting experiments on film to judge student performance against a standard set of criteria. Results suggest increases in observational objectivity and precision as well as…

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)
