Resistance probes for the laboratory can be divided into two main categories: (1) those involving direct use of resistance; and (2) those involving an indirect use of resistance. Described are several applications of both types related to chemistry and physics. (RH)

Described is an exercise which examines the effect of reading aloud a technical passage of science material while the heart is monitored by a computer. The experimental setup, design, and data analysis are discussed. (CW)

Described is an approach that uses a computer spreadsheet program to calculate entropy change at constant temperature and pressure. The calculated values can be used in an associated graphing program. (CW)

Surveys the types of computers being used in high school and university chemistry courses. Identifies types of hardware found on Apple and MS-DOS computers. Makes recommendations for the upgrading of current equipment. (ML)

Presented are 25 short articles which represent a variety of topics. Included are laboratory exercises, games, demonstrations, models, activities, teaching methods, notes regarding procedures and updates of scientific information. (CW)

Explored are ways in which spreadsheets can be used in the teaching of chemistry. Some of the limitations of using algebraic modelling tools are highlighted. Several example applications are provided. (CW)

Describes the underlying pattern that, once seen, will allow students to describe the shape of any hydrogen orbital. Involves the exponential form of the orbitals. Provides computer-generated plots of this concept. (CW)

The interfacing of a physical pendulum to an Apple IIe computer and the physic instruction associated with it are discussed. Laboratory procedures, software commands, and computations used in this lesson are described. (CW)

Two Hypercard stacks are reviewed including "Amino Acids," created to help students associate amino acid names with their structures, and "DNA Teacher," a tutorial on the structure and function of DNA. Availability, functions, hardware requirements, and general comments on these stacks are provided. (CW)

Presented is an illustration of the use of a computer spreadsheet program, Microsoft Excel version 1.5, for solving complicated chemical problems. Examples of spreadsheet output are provided. (CW)

Describes a spreadsheet computer program which can be used with an Apple Macintosh computer to perform a multitude of calculations. Discusses two types of calculations taught in general chemistry. Demonstrates how to use the spreadsheet to calculate mass percent and the formula of a compound. (TW)

Reviews three computer software packages for chemistry education including "Osmosis and Diffusion" and "E.M.E. Titration Lab" for Apple II and "Simplex-V: An Interactive Computer Program for Experimental Optimization" for IBM PC.
