The assumptions common to all capture-recapture models for estimating population size are reviewed. A simulation using either a playing board, counters, and dice or computers is described. Classroom implications of using the board game are discussed. (KR)

Provides reviews of four computer software packages designed for use in science education. Describes courseware dealing with a variety of tips for teaching physics concepts, chemical reactions in an aqueous solution, mitosis and meiosis, and photosynthesis. (TW)

Describes efforts of members of the biology and physics departments of Paisley College (Scotland) to develop a simple light-emitter-detector arrangement adapted as a colorimeter interfaced with a microcomputer for use by undergraduate students. Discusses the setup and provides a computer program in BASIC to run it. (CW)

A technique for the numerical identification of bacteria using normalized likelihoods calculated from a probabilistic database is described, and the principles of the technique are explained. The listing of the computer program is included. Specimen results from the program, and examples of how they should be interpreted, are given. (KR)

Describes an interactive simulation model which can be used to demonstrate population growth with discrete or overlapping populations and the effects of random, constant, or density-dependent mortality. The program listing (for Commodore PET 4032 microcomputer) is included. (Author/DH)

This CD-ROM is designed for classroom and individual use to teach and learn about food chains and food webs. Integrated animations, custom graphics, three-dimensional representations, photographs, and sound are featured for use in user-controlled activities.
