Described is an interdisciplinary unit on animal care for elementary school students. Included are research strategies; a semantic map; ideas for integrating reading, writing, and science; and a discussion of the benefits of using imagination in learning. (CW)

Described is an experiment in which students are able to synthesize an unnatural compound having the odor and flavor of coconuts. Laboratory equipment, procedures, and analysis of the product are discussed. (CW)

Described is an alternative method of culture isolation that uses streaking on specialized media. An activity in which different media are tested for selectivity is presented including a list of materials and procedures. A chart of colony morphology is given. (CW)

Describes three activities: "Solar Approach to Ohm's Law," dealing with the Ohm's law and the inverse square law; "Using LED's to Demonstrate Induced Current," showing Faraday's law and Lenz's law by using light emitting diodes (LEDs); and "The Helium-Filled Organ Pipe," discussing a discrepancy between theory and experiment. (YP)

Explains strategies for motivating and getting student's attention in science. Presents a laboratory procedure for generating hydrogen using an Erlenmeyer flask and a one-holed stopper apparatus to fill a balloon which is used to produce a dramatic explosion. Safety precautions are cited. (RT)

Describes a lesson which integrates thinking, writing, and physics. Provides examples of student involvements, a list of typical topics, and additional notes to the teacher. (RT)

Describes a demonstration which allows students to witness a type of continuous spectrum and an absorption spectrum. Provides a diagram and explanation for the construction of an absorption box. (RT)

Describes a thin film rectangular dielectric waveguide and its laboratory use. Discusses the theory of uniaxial thin film waveguides with mathematical expressions and the laboratory procedures for a classroom experiment with diagrams. (Author/YP)

Describes experiences, or "lab puzzles," which will help students develop problem-solving skills in a laboratory setting. Outlines procedures for developing techniques, setting boundaries, and finding the number of molecules of water in Lake Erie. (RT)

Describes a method for making holograms viewable in white light without the problem of vibrations. Presents diagrams which show the arrangement for construction, viewing procedures, and a device for generating holograms. A list of supplies is included. (RT)

Presents an experiment to measure the threshold limit of the adhesion of water. Discusses types of thresholds and pseudo thresholds. Provides 13 examples of thresholds in science. (MVL)

Described is a science activity for intermediate grades which uses science skills to solve a mystery. Fingerprints, footprints, chromatography, invisible ink, and microscopic analysis are used in the activity. Observation, data analysis, and deductive reasoning are stressed. (CW)

Explains an activity which can be used to compare the effect of temperature on the rate of chemical reactions to the metabolic reactions that take place within the body. Outlines directions and materials needed to perform the experiment. Lists a number of the body's defenses against extremely low temperatures. (RT)

Explains how a science teacher's experiences as a chimney sweep were used to provide new material for introducing and reinforcing scientific concepts. Photographs of chimney inhabitants were used as the raw data for student inquiries into the ecological processes taking place in and around chimneys. (RT)

This paper argues the value of drama processes in science classrooms as a way of enabling students to learn openly from and with each other and of enhancing higher order learning skills. Role-playing, focus, and tension are described as constructs to guide the pedagogy of drama processes. (YP)
