Describes an apparatus that uses a microcomputer as a timing device in which the Coefficient of Restitution (COR) is measured. Diagrams of a circuit for timing measurements and a flow chart of a program that measures COR are provided. A list of COR for some common objects is also included. (CS)

Presents details of anodic stripping analysis (ASV) in college chemistry laboratory experiments. Provides block diagrams of the analyzer system, circuitry and power supplies of the automated stripping analyzer, and instructions for implementing microcomputer control of the ASV. (CS)

Offers suggestions for making good use of a single microcomputer in classes with large numbers of students. Strategies described include in-class demonstrations, laboratory station activities, group activities, enrichment activities, and data collection techniques. Diagrams of room arrangements to accomplish the strategies are included. (BC)

Provides rationale for and description of an acid rain game (designed for two players), a problem-solving model for elementary students. Although complete instructions are provided, including a copy of the game board, the game is also available for Apple II microcomputers. Information for the computer program is available from the author.…

Describes a sequence of five computer programs (listings for Apple II available from author) on tactic responses (oriented movement of a cell, cell group, or whole organism in reponse to stimuli). The simulation programs are useful in helping students examine mechanisms at work in real organisms. (JN)

Describes classroom use of a computer program originally published in Creative Computing magazine. "The Nuclear Power Plant" (runs on Apple II with 48K memory) simulates the operating of a nuclear generating station, requiring students to make decisions as they assume the task of managing the plant. (JN)

Microcomputers are commonly interfaced to external devices in scientific, industrial, and consumer settings for data acquisition and for control. The general problem under consideration is the task of taking measurements of some continuous phenomenon, transforming them into digital form, and storing the data in the microcomputer for later use.…

Discusses the use of the Bank Street Laboratory sound probe in activities focusing on various aspects of sound. Also examines what students were learning during the activities (such as students understanding what is meant by the pitch of a tone). (JN)

Describes three experiments: (1) "Liquid Flow from Orifices"; (2) "Microcomputer-Controlled Investigation of Battery Discharge and Recovery"; and (3) "Measurement of the Speed of Sound." Drawings and diagrams accompany each. (RT)

Describes two games which may be used with pairs or teams of students in earth/space science courses to reinforce and enrich content and to review subject matter. A microcomputer program in BASIC II is provided. (CS)

Describes a computer program, "Activation Energy," which is designed for use in physical chemistry classes and can be modified for kinetic experiments. Provides suggestions for instruction, sample program listings, and information on the availability of the program package. (ML)

Suggests cooperative learning projects if only one microcomputer is available for a large class. An example of such a project using a program dealing with correlating sedimentary rock layers through cross-sectional analysis is described. Instructional strategies and academic objectives of the three-module program are included. (JN)

Describes computer measurement of capacitor charge decay, change of fringe width with color, computer simulation of color mixing, Doppler effect/carrier waves, gravitational waves, microwave apparatus, computer simulation of Brownian motion, search coils and problems with the teaching of the relationships of velocity, frequency, and wavelength in…

Described is how spreadsheet and problem solver microcomputer programs may assist students in performing mathematical calculations. Discussed is the application of the equation solver "MathCAD" to various areas in the undergraduate curriculum. (KR)

Describes the monitoring of the redistribution of blood by using a technique which detects changes in the center of gravity of the body. Provides information about the principles and application, construction of apparatus, operating routines, and use of the computer as a recorder. Includes suggested investigations, demonstrations, and diagrams.…
