A computer program that simulates the random evolution of a metabolic pathway is given. The program shows that natural selection preserves favorable traits if they occur in a specific sequence. (KR)

Uses chaos theory to investigate the nonlinear phenomenon of population growth fluctuation. Illustrates the use of computers and computer programs to make calculations in a nonlinear difference equation system. (MDH)

Explains the use of the 3-dimensional analytic geometry method to find values for a field geology problem. Gives a description of the mathematical theory for this method which can be applied to data obtained by drilling as well as open surfaces, and a computer program. (RT)

Provides a review of both the Apple and IBM versions of ENZPACK, a software package which is designed to assist in the teaching of enzyme kinetics in courses where this topic is treated in some depth. (TW)

Partners in Science students, aided by community professionals, learn science by designing and conducting their own research. Partners in Science brings the community and schools closer together through a mentorship program. Scientists, in fields ranging from wildlife biology to space physics, are in frequent contact with classes and home-schooled…

Predicting weather conditions is a topic of interest for students who want to make plans for outside activities. This paper discusses the development of an inexpensive computer-interfaced classroom weather station using an Apple IIe computer that provides the viewer with up to the minute digital readings of inside and outside temperature,…

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)

Presents experiments to measure the velocity of sound through metals and other amorphous materials. Describes the equipment used to make the measurements and the possibility of interfacing with a microcomputer. (MDH)

Reviews Apple computer science programs that are useful in a laboratory setting. Includes laboratory simulations, uses of Apple as a functioning lab instrument, and dissection programs. (ML)

Discusses the possibility of having chemistry students do their own computer programing that could then be used to solve problems in general chemistry. Describes such an effort at Eastern Washington University. Provides examples of some of the student programs and printouts. (TW)

Describes a new software package for the Apple Macintosh computer which can be used to create elaborate simulation models in a fraction of the time usually required without using a programming language. Illustrates the use of the software which relates to water usage. (TW)

Described is a method of evaluating student chemistry laboratory reports using electronic reporting from locally developed macros. Examples of the input template, the grade report template, and input and grading programs are given. Results of a survey of students and teachers evaluating the program are reported. (MDH)

Discusses the use of a computer program designed to solve the mathematical model associated with soil nutrient uptake by plant roots and to predict the nutrient uptake. Describes a user-friendly personal computer version of this program. (TW)

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)

Describes a heat capacity experiment designed to provide an interactive environment between the student, the experiment, and the computer. Discusses computer software that has been developed so that the entire interaction can be coordinated from the computer keyboard. (TW)
