Describes a simple undergraduate experiment in chemistry dealing with the "solvent effects" in nuclear magnetic resonance (NMR) spectroscopy. Stresses the importance of having students learn NMR spectroscopy as a tool in analytical chemistry. (TW)

Describes three situations in which computer software was used in a chemistry laboratory. Discusses interfacing voltage output instruments with Apple II computers and using spreadsheet programs to simulate gas chromatography and analysis of kinetic data. Includes information concerning procedures, hardware, and software used in each situation. (CW)

Presents a laboratory exercise suitable for advanced placement biology or chemistry classes. Discusses the theoretical approach, preparation and standardization of reagents, and results. Emphasizes standard analytical procedure and chelometric titration. (CW)

Describes an experiment designed to use the ability of duckweed to convert the secondary hydroxyl moieties into ketone groups. Discusses the preparation of plant material, materials, procedures, and results for this biotransformation experiment for undergraduate students. (CW)

Describes a series of activities and demonstrations involving the science of soap bubbles. Starts with a recipe for bubble solution and gives instructions for several activities on topics such as density, interference colors, optics, static electricity, and galaxy formation. Contains some background information to help explain some of the effects.…

Described is the separation of dyes using a conventional liquid chromatographic pump and a glass column. Included are the preparation of the column and dye separations. (CW)

Discusses how problem-solving networks can be incorporated into courses. Reports on the development of a new style of pictorial network that can assist students in the handling of experimental data. (CW)

Describes experiments designed to measure the oxygen content in the atmosphere and related areas in the high school laboratories. Considers the application of these activities to other programs. Includes a description of the binuclear complex and recommended procedures. (CW)

Criticizes the way organic chemistry teaching laboratory experiments are approached from the viewpoint of physical chemistry. Compares these experiments to cooking. Stresses that what matters is not the practice of the finger skills of organic chemistry but practice in the style of thinking of organic chemists. (CW)

Describes an experiment for undergraduate chemistry laboratories involving a chemical found in plants and some sea animals. Discusses collection and identification of material, a hemolysis test, preparation of blood-coated agar plates, and application of samples. (CW)

Describes a magic show designed to encourage young children in physics and chemistry. Discusses how a little "razzle-dazzle" can effect children positively. Tells how to organize and perform a magic show. Details six tricks that focus on principles of chemistry or physics. (CW)

Describes an experiment designed to give accurate values for both the absolute zero of temperature and the gas constant using very simple apparatus. (TW)

Describes two experiments in college chemistry which use microcomputers. One experiment deals with chemical oscillations, while the other involves colorimeter titration with laser excitation and computer-interfaced endpoint detection. (TW)

Provides a listing of 35 demonstrations designed to generate interest in organic chemistry and help put points across. Topics include opening lecture; molecular structure and properties; halogenation; nucleophilic substitution, alkenes and dienes, stereochemistry, spectroscopy, alcohols and phenols, aldehydes and ketones; carboxylic acids, amines,…

Describes use of computer simulation which generates bird songs so that students can analyze song motifs and sequences as an introduction to descriptive analysis of behavior in an animal behavior course. Advantages of the simulation are discussed together with computer hardware/software needed and data presentation, analysis, and generation…
