Israeli tenth-grade students completed a chemistry laboratory course by either performing the experiments or by viewing films of the experiments. Among the results of an attitude test given to both groups was that students find personalized laboratory more effective than films in promoting their interest in chemistry. (MLH)

Describes an undergraduate organic chemistry experiment in which papain is used as a catalyst for the stereospecific formation of an insoluble anilide from a racemic benzoylamino acid. (MLH)

Discusses the relationship between adsorption isotherms and elution peak shapes in gas chromatography, and describes a laboratory experiment which involves the adsorption of hexane, cyclohexane, and benzene on alumina at different temperatures. (MLH)

Presented are two science demonstration projects: (1) the simulation of a magnetic survey utilizing a bar magnet buried in a sand box and (2) an investigation of the reaction between lead nitrate and sodium hydroxide. (SL)

Describes a study in which participants in a summer institute for secondary science teachers performed a series of experiments with a radio telescope. Concludes that a radio astronomy teaching facility would encourage students to use their own initiative and strategy in working with the scientific concepts involved. (MLH)

Includes five brief articles on: solar-heating demonstration equipment, mercury or sodium vapor lamp spectroscopy, an apparatus for simulating variable stars, a voltage-to-frequency converter, and an introductory absorption experiment for low-energy beta particles. (MLH)

In the applications of instrumental analysis lessons, advanced instruments with the needed experiments are needed. During the lessons it is a fact that the more experiments are performed, the more learning will be. For this reason, experiments that do not last long and should be performed with more simple instruments and that increase students"…

While a science teacher needs to be thoroughly grounded in science content and methodology, the science teacher also needs to be a reading teacher. Science experiments and demonstrations need to be integrated with reading in the science curriculum. Reading in science helps students with comprehension, the development of concepts and…

This book contains the student edition of the Environmental Inquiry curriculum series developed at Cornell University. It is designed to teach learning skills for investigating the behaviors of non-native and native species and demonstrate how to apply scientific knowledge to solve real-life problems. This book focuses on strange intruders…

This short article consists of some thoughts derived from a longer paper (Palmer, 1992), together with some more recent ideas. I became interested in buckminsterfullerene (Buckyballs) as a result of an E-Mail discussion of the topic in 1991. The chemistry of buckyballs is now evolving very rapidly and is gradually creeping into school…

This selected collection of How-To-Do-It articles published in the American Biology Teacher during the past six years presents experiments that can be conducted safely under properly trained and responsible teacher supervision. Contents include: (1) "General Biology and the Nature of Science"; (2) "Cells and Molecules"; (3) "Microbes and Fungi";…

In recent years, there has been a growing interest in the use of graphing technology for the teaching of mathematics. This interest has been, in part, sparked by the recommendations of the National Council of Teachers of Mathematics (NCTM) Standards and "Everybody Counts: A Report to the Nation on the Future of Mathematics Education."…

The "CSE Program Evaluation Kit" is a series of nine books intended to assist people conducting program evaluations. This volume, the third in the kit, discusses the logic underlying the use of quantitative research designs, including the pretest-posttest design, and supplies step-by-step procedures for setting up and interpreting the…

Flowers are not only pretty, they are also one of the key elements in the process of plant pollination and reproduction that goes from flowers to fruits to seeds! In All About Plant Pollination: Fruit, Flowers & Seeds, young scientists learn about the different parts of a flower through the use of microscopic photography and detailed diagrams.…

Discusses the theory and experimental procedures for using Young's eriometer to determine the diameters of blood corpuscles, lycopodium powder, and wool fibers. (CC)
