Describes an experiment in which a microcomputer was programed to function as a transfer function analyzer to investigate the dynamics of stirred vessels. The main objective of the experiment is to illustrate the theory and application of the pulse test (a method of determining the transfer function of a process). (JN)

Describes a chemistry laboratory software package for interfacing the Apple IIe for high school and introductory college courses. Topics include: thermistor calibration, phase change, heat of reaction, freezing point depression, Beer's law, and color decay in crystal violet. Explains the computer interface and the tools needed. (MVL)

Reports on acquiring and analyzing enzyme kinetics data using Apple microcomputers. Describes the experimental background and procedures, instrumentation, cautions, and construction aids. Cites applications which illustrate the use of a computer in a laboratory exercise. (RT)

Examines two computer interfaced lab experiments: 1) discusses the automation of a Perkin Elmer 337 infrared spectrophotometer noting the mechanical and electronic changes needed; 2) uses the Gouy method and Lotus Measure software to automate magnetic susceptibility determinations. Methodology is described. (MVL)

Discusses the use of a computer software package called ASYST for general laboratory computing. Describes the software's capacity for acquiring data in a flow injection analysis experiment. Reviews the series of commands used by students in carrying out the experiment. (TW)

Discusses the problems created by the insufficient number of major data collection and analysis instruments in most college chemistry courses. Suggests the use of less expensive microcomputer-controlled instrument emulators, which resemble the actual instruments. Discusses the application of one such emulator in an instrumental analysis course.…

Presents an approach for building an inexpensive control engineering laboratory to support control courses in an undergraduate engineering program. Outlines the use of simple amplifier circuits and small personal computers in performing control experiments. Proposes an optimum configuration of the laboratory for minimum servicing and adequate…

Describes a first-year chemistry laboratory experiment which uses a simple computer program written in BASIC, to analyze data collected by students about the density of a set of marbles. A listing of the program is provided, along with a sample printout of the experiment's results. (TW)

Science projects which can be used by high school students who have minimal experience with computers or electronics are presented in this book on laboratory interfacing. These laboratory interfacing projects include either the connecting of measuring instruments directly to a computer or using a computer to control external devices. All of the 14…
