Reviews a chem-study experiment in which students weigh and compare equal volumes of gases and enter their data into a microcomputer. Benefits of using the microcomputer include: (1) data table generation; (2) elimination of calculation errors; (3) student conclusions which are meaningful; and (4) efficient grading time for the teacher. (DH)

Includes the complete listing for a computer program which draws the best curve to fit calibration data obtained from a set of five standard solutions. (DH)

Describes a method for making a simple, inexpensive apparatus which can be used to determine Planck's constant. Provides illustrations of a circuit diagram using one or more light-emitting diodes and a BASIC computer program for simplifying calculations. (RT)

Details the features of BASIC used in mathematics programming and provides the information needed to translate between the Apple II and IBM PC computers. Discusses inputing a user-defined function, setting scroll windows, displaying subscripts and exponents, variable names, mathematical characters and special symbols. (TW)

Discusses chaotic behavior (movement) in a nonlinear system using LOGO programs. Presents several examples with program listings. (MVL)

Considers the development of a computer program for interactive, screen-oriented problem solving. Provides theoretical background and program development to determine internal energy, heat capacity, and entropy. Lists the program written in BASIC for Apple II computers. (MVL)

Provides a method to use superscripts and subscripts on the screen by using graphics screen modes. Gives two methods and provides a listing of a sample BASIC program. (MVL)

Identifies six computer-oriented approaches to teaching concepts in chemistry. Describes courseware and equipment involved in various experiments dealing with such topics as polymer configurations, stepper motors, conductometric titration, kinetic spectrophotometry, and overlap integrals. (TW)

This manual was developed for use as a "how to" training device and provides a step-by-step introduction to using AppleWorks in the database mode. Instructions are given to prepare the original database with the headings of the user's choice. Inserting information records in the new database is covered, along with changing the layout of…

Discusses the ISCS/FIRN Test Item Database, which contains 10,000 juried science questions that can help teachers prepare tests. Describes the process by which teachers can access the database and download certain questions into their own microcomputer. Provides lists from a sample search done using the various menus available. (TW)
