Describes a set of computer-based learning modules designed to teach nonscientists to think and reason like scientists. Discusses the intent of the 10 dialogs in this series. Gives ideas for use in science classes. (CW)

Provides background information on the equipment and knowledge necessary to do an astronomy activity on the earth's rotation. Details an activity in which students can measure the rotation of the earth using a camera and the stars. (CW)

Describes an experiment involving pineapples and gelatin that allows students to investigate the conditions that typically render an enzyme functionless, similar to the effect of nerve gasses. Discusses the materials, procedures, and results, drawing analogies to the effects of a nerve gas. (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)

Discusses some of the principles of classroom management and discipline that can be used in the classroom. Includes avoiding distracting verbal exchanges, a management system, the use of verbal reprimand, room arrangements and isolation. Concludes that planning and attention to classroom management are worth the effort. (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 a way to use computers in teaching chemistry, in this case in a demonstration lesson on supercooling using a thermister in a game port to interface the computer with cooling phenyl salicylate. Discusses the advantages over the traditional method of instruction. (CW)

Deals with a fungus that plays an important role in the forests of Asia as a decomposer of recently dead trees and in agriculture as an important edible mushroom. Describes how to culture these mushrooms including materials, conditions, and troubleshooting. Gives ideas for classroom activities. (CW)

Discusses the value of memorized factual material in science. Describes the use of mnemonic devices to facilitate memorization. Provides a list of 14 mnemonic devices commonly used in science other than ROY G. BIV, which is used to remember the colors of the visible spectrum. (CW)

Reviews four software packages available for IBM PC or Apple II. Includes "Graphical Analysis III"; "Space Max: Space Station Construction Simulation"; "Guesstimation"; and "Genetic Engineering Toolbox." Focuses on each packages' strengths in a high school context. (CW)
