Reviews scientific research and research projects which have been undertaken by secondary level students. (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)

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

Describes a laboratory experiment suitable for undergraduate students which illustrates the oxidative coupling of phenols. (SL)

Describes experiments on the properties of bile salts in teaching physical chemistry for biologists. (SL)

Describes an experiment using an analog computer which allows students to work with familiar problems, and to program the computers themselves. (SL)

Describes an experiment to distinguish aldehydes from ketones utilizing a recently introduced reagent. (SL)

Describes a three period project type laboratory experiment designed to maintain student interest. (SL)

Described are the morphology, eating habits, and habitats of three types of Bryozoan colonies. Information on where to collect these organisms and how they can be cultured are included. Suggestions are given for lab experiments that can be done with type three colonies and Euglena. (MA)

At the Center for Biomedical Education at the City University of New York, nutrition is integrated into the chemistry-biochemistry sequence of a six-year B.S.-M.D. program. Students perform an actual analysis of a sample of their own food, learning basic techniques and concepts, and also carry on experiments with rats on other diets. (Editor/LBH)

Presents three demonstrations suitable for undergraduate chemistry classes. Focuses on experiments with calcium carbide, the induction by iron of the oxidation of iodide by dichromate, and the classical iodine clock reaction. (ML)

Presents a laboratory exercise that illustrates stoichiometry, limiting reagents, and proportionality. Highlights the safety and low cost factors of this exercise. Outlines procedures for the students. (ML)

Deals with a diffraction experiment using wrapping paper. Provides a magnified picture of the paper, a diffraction diagram, and some instructional information. (YP)

Provides information appropriate for introductory lectures on photoelectric effects in membranes. Describes the apparatus and supplies required for laboratory exercises. Outlines typical laboratory exercises. Identifies the chromophores known to induce photoelectric effects. Concludes that this topic can provide useful subjects for undergraduate…

Twenty teachers were selected to teach 20 elementary classes a science lesson featuring laboratory experience in small groups. Ten teachers were alerted to the possibilities of sexism in the physical sciences. Results indicated girls in mixed-sex work groups participate less when the teacher is less aware of sexism problems.
