Safety procedures used by Department of Chemistry at the University of Akron are discussed. These include policy that no chemicals are stored in the teaching laboratories. Instead, dispensing stockrooms are used to service the laboratories. Other aspects discussed include ventilation procedures and development of microprocessor use in stockrooms.…

Two computer-oriented chemistry laboratory simulations are described. The material focuses on acid-base titration and an ideal gas simulation. (MP)

Describes a laboratory designed to give students practical experiences with experimental phenomena discussed in lectures, focusing on laboratory organization and typical experiment. In addition to a list of experiments, three exercises are discussed: fluorescence/laser, ferromagnetic domains, and thermal population (which uses PET computer…

Describes development of microcomputer-controlled gamma scintillation spectrometer and chromatographic data analyzer, including design and construction of interface electronics and production of software. Includes diagrams of electric circuits and project evaluation indicating that both instruments functioned as intended. (JN)

The University of Georgia (UGA) biosafety program was initiated in response to requirements for recombinant DNA experiments rather than laboratory-acquired infections. This and other environmental safety programs at UGA are described, considering three of the four recognized levels of biocontainment. A fire extinguisher inspection computer program…

Describes laboratory procedures, demonstrations, and classroom activities/materials, including chi-square tests on a microcomputer, an integrated biology game, microscope slides of leaf stomata, culturing soil nematodes, technique for watering locust egg-laying tubes, hazards of biological chemicals (such as benzene, benzidene, calchicine,…

Briefly reviews arguments for and against high school science laboratory instruction and suggests using the microcomputers as a laboratory instrument. How the microcomputer-based laboratory (MBL) works is explained and some hardware and software packages are noted. (MBR)

The Apple II microcomputer program described allows instructors with minimal programing experience to construct computer models of psychological phenomena for students to investigate. Use of these models eliminates need to maintain/house/breed animals or purchase sophisticated laboratory equipment. Several content models are also described,…

The learning center is a cost-effective and popular way to introduce hearing impaired students and their teachers to microcomputers. (A brief listing of software companies and computer periodicals is included.) The use of the Apple microcomputer in a learning center in a school for the deaf is discussed. (CL)

Describes a simple and inexpensive interface to be used for data acquisition and control of some experiments in an undergraduate physics laboratory. Two specific applications are presented. Seven references are listed. (Author/MBR)

Emphasis on interfacing -- the various processes for passing information into or out of computers -- is suggested. Why the Texas Instruments microcomputer is plausible for this is noted, followed by specific interfacing suggestions, including programs for a timer and the assembly language subroutine. (MNS)

Describes an experiment on the simultaneous determination of chromium and magnesium by spectophotometry modified to include the Generalized Standard Addition Method computer program, a multivariate calibration method that provides optimal multicomponent analysis in the presence of interference and matrix effects. Provides instructions for…

Describes two computer programs for use in process design courses: an easy-to-use equipment cost estimation program based on latest cost correlations available and an economic evaluation program which calculates two profitability indices. Comparisons between programed and hand-calculated results are included. (JM)

A teacher of deaf high school students describes considerations in developing a computer lab, including equipment selection, class and subject scheduling, and suitable software. Examples of software used in his lab are cited, including Mathware's Math City and Apple's SUPERMATH program. (CL)

Presents a laboratory experiment that was developed to acquaint physics students with field-effect transistor characteristics and circuits. Computer-drawn curves supplementing student laboratory exercises can be generated to provide more permanent, usable data than those taken from a curve tracer. (HM)
