This document contains the listings for 46 computer programs which are designed to teach various concepts in chemistry and physics. Significant time was spent in writing programs in which students would input chemical and physical data from their laboratory experiments. No significant time was spent writing drill and practice programs other than…

Discusses simple interval timers for microcomputers, including (1) the Jiffy clock; (2) CPU count timers; (3) screen count timers; (4) light pen timers; and (5) chip timers. Also examines some of the general characteristics of all types of timers. (JN)

Describes: (1) spreadheet programs (including VisiCalc) for experiments; (2) event-driven data acquisition (using ADALAB with an Acculab Infrared Spectometer); (3) microcomputer-controlled cyclic voltammetry; (4) inexpensive computerized experiments; (5) the "KC? Discoverer" program; and (6) MOLDOT (space-filling perspective diagrams of…

Describes a computer program that students use to check their suggestions of possible lines of investigation during a microbiology exercise, the results of procedures, and the decisions made on the basis of experimental evidence. Effectiveness of the program and practical aspects of the investigation are considered. (DH)

Presented is a three-hour instrumental analysis experiment which allows study of software data-handling methods. These methods include sampling, boxcar averaging, smoothing, ensemble averaging, and digital filtering. Use of the program should provide students with a better idea of advantages and disadvantages of using such software data-handling…

Describes (1) interfacing the Commodore VIC-20 using joystick game ports; (2) a chromatographic integrator for the TRS-80; (3) upgrading input/output capabilities of the TRS-80 color microcomputer; (4) IBM PC interfaced to a Perkin-Elmer DSC-1 differential scanning calorimeter; and (5) an undergraduate experiment in which students design a…

Describes a user-friendly computer program that will analyze the data from one kinetics experiment for 84 different rate laws (sets of partial orders). Information on obtaining the program (written in VAX-Basic and implemented on a VAX-780 computer), its instruction, and related programs are included. (JN)

Describes an experiment which allows students to identify the nature of the time-course for chymotrypsin and to obtain mechanistic information on the two kinetic phases in terms of their concentration dependence. Also describes the computer simulation (available from the author) used in the experiment. (JN)

Describes: (1) a FORTH-language, computer-controlled potentiometric titration; (2) coulometric titrations using computer-interfaced potentiometric endpoint detection; (3) interfacing a scanning infrared spectrophotometer to a microcomputer; (4) demonstrations of signal-to-noise enhancement (digital filtering); (5) and an inexpensive Apple…

Describes three computer programs which operate on Apple II+ microcomputers: (1) a menu-driven graph drawing program; (2) a simulation of the Millikan oil drop experiment; and (3) a program used to study the half-life of silver. (Instructions for obtaining the programs from the author are included.) (JN)

An interactive computer program in microbial genetics is described. The simulation allows students to work at their own pace and develop understanding of microbial techniques as they choose donor bacterial strains, specify selective media, and interact with demonstration experiments. Sample questions and outputs are included. (DH)

Describes activities, games, experiments, demonstrations, and computer-oriented exercises in all science areas. Topics include energy flow through a marine ecosystem, using 2,4-dichlorophenoxyethanoic acid to demonstrate translocation in plants, use of the dichotomous key, use of leaf yeasts to monitor atmospheric pollution, and others. (JN)

Discusses modifications in the fatty acid monolayer experiment to reduce the inaccurate moleculary data students usually obtain. Copies of the experimental procedure used and a Pascal computer program to work up the data are available from the authors. (JN)

Suggests purchasing a digital multimer (DMM) with an IEEE-488 option to interface an instrument to a microcomputer, indicating that a DMM is well protected from overloads and is easy to connect. An example of its use in an experiment involving hydrolysis of tertiary butyl alcohol (with program listing) is given. (JN)

Faced with beginning the school year without the necessary chemicals for experiments in a newly adopted chemistry textbook, a department chairperson conceived the idea of supplementing the textbook with simulated experiments on microcomputers. The methodology used to select the appropriate software is described, with suggestions for some new…
