This is a general evaluation and description of a museum for children ages two through 12 that was begun by a group of citizens in Denver, Colorado. The evaluation shows that the museum is serving the community successfully and has met its broad goal of giving children an opportunity to develop positive self-concepts and to grow cognitively…

Provides some background information on acid deposition. Includes a historical perspective, describes some effects of acid precipitation, and discusses acid rain in the United Kingdom. Contains several experiments that deal with the effects of acid rain on water quality and soil. (TW)

Contains 21 articles ranging from instructional experiments to topical information. Deals with investigation of plant rust diseases, using computers to teach biology, plant roots, a biotechnology curriculum, the corrosion of oxides, electrochemical simulations, the Reimer-Tiemann reaction, the oxidation of aldehydes, and the extraction of iodine…

Describes the use of a precalibrated stainless steel thermistor, interfaced with an Apple computer, in chemistry experiments. Discusses the advantages of "instant" temperature readings in experiments requiring that readings be taken at certain intervals. Outlines such an experiment which investigates freezing point depressions. (TW)

Discusses some of the chemical concepts that the United States Space Program illustrates. Describes ways to use the space program to motivate students to learn chemistry and its relationship to the world. Provides examples of classroom applications to environmental chemistry and biochemistry in studying the operation of the space shuttle. (TW)

Discusses some of the advantages of using overhead projectors to demonstrate chemistry experiments. Provides a list of guidelines and equipment for these types of demonstrations. Describes 21 simple demonstrations that can be done in chemistry classrooms that require minimal equipment and cost. (TW)

Describes the learning style inventory and learning cycle developed by David Kolb. Discusses the learning cycle's four stages as concrete experience, reflective observation, abstract conceptualization, and active experimentation. Offers an example from a chemical engineering class in which Kolb's ideas are used in an effort to improve instruction.…

Examines the physical properties of the ocean (including the composition of seawater; waves, currents, and tides) and the topography of the ocean floor. Included are (1) activities on oceans, saltwater, and the sea floor; and (2) questions, and a puzzle which can be copied. (Author/RT)

Details 26 experiments designed for use in secondary or college science classes. Includes activities for physical and biological sciences. Describes procedures, materials, safety, and analyses appropriate for each. (CW)

Gives the background history and chemistry of modern day chemical warfare from World War I to the present. Provides discussion questions to stimulate deeper thinking on the issue. Contains a discussion activity called "Can New Chemical Weapons Lead to Humane Warfare?" (CW)

Describes the development of and activities used with rubber powered paper vehicles as science projects and instructional devices in junior high and high school science classes. Includes plans and instructions for building the "Lou-Vee-AirCar." (CW)

Describes eight applications of the use of computers in teaching chemistry. Includes discussions of audio frequency measurements of heat capacity ratios, quantum mechanics, ab initio calculations, problem solving using spreadsheets, simplex optimization, faradaic impedance diagrams, and the recording and tabulation of student laboratory data. (TW)

Describes an exercise developed at the University of Natal (South Africa) in which students visit a plant which manufactures a variety of lead compounds. Outlines the procedures for the laboratory preparation of lead compounds that students prepare with samples they collected at the plant. (TW)

Investigated the cognitive engagement of students in grades 4-6 who received science lessons that varied in the level of cognitive content, procedural complexity, and social organization. The variables did not significantly affect student involvement. Cognitive engagement was similar for tasks judged as low and high in difficulty. (SKC)

Describes two methods to teach radioactive decay to secondary students with wide ranging abilities. Activities are designed to follow classroom discussions of atomic structure, transmutation, half life, and nuclear decay. Includes "The Tasmanian Empire: A Radioactive Dating Activity" and an exercise to teach concepts of half life without…
