Describes a blood coagulation test developed by two high school biology students. Although the test lacks some precision, results indicate that the technique is comparable to standard methods used in laboratories. (MA)

Describes an experiment for general chemistry students for analyzing bathroom cleansers. (SL)

Describes a laboratory exercise illustrating the use of the Cannizzaro reaction in synthesis, the production of commercial resin, and the importance of natural products in industrial chemistry. (SL)

Describes an experiment utilizing the Solvay synthesis of sodium hydrogen carbonate to teach students to organize and plan a synthesis procedure. (SL)

Reviews experiments performed in a mobile spectroscopy laboratory. (SL)

This experiment, mixing solutions of potassium iodide and lead nitrate to give a bright yellow lead iodide precipitate, often leads students into other topics such as making paint from the precipitate. (BB)

Reports on apparatus for generating Lissajous figures, projecting Poisson's spots, photographing diffraction patterns, electric heating, and projecting moving longitudinal waves on an oscilloscope. (SL)

Presents four science experiments for the junior high level relating to electric switches, a chemical card game, combustion energy, and chromatography. (SL)

Describes the use of an interactive computer terminal for introductory laboratory experiments. (SL)

Reports an experimental procedure for a course in physical organic chemistry to illustrate correlation between structure and reactivity. (SL)

Describes two procedures for the conversion of eugenol to vanillin

Presents a differential thermal analysis system constructed mainly from commercially available modular units. (SL)

Folsomia candida is presented as an ideal organism for population studies that can be carried out cheaply and easily in school laboratory conditions. Means of identifying, obtaining, and culturing these organisms are described together with some indication of the kinds of investigations which can be performed. (Author/MA)

Callus induction from species of Haworthia can be done quickly in the laboratory with minimal equipment to study tissue dedifferentiation and cellular redifferentiation. It is shown that the cultured cell can also be used to study and evaluate the effects of various mutagens, carcinogens, and pesticides in controlled environments. (Author/MA)

Describes an experiment for the determination of water/lipid distribution ratios of drugs. (SL)
