A new Microsoft Excel spreadsheet design that enables a prompt calculation of rate constant, k values and associated errors and also addresses less common features such as the choice of an experimental curve's extent is presented. To complete the spreadsheet design, several highlights and squared colored boxes were included to assist the user and…

A simple Vernier software and Technology LabPro unit was used to interface a computer with a Durrum model 110 stopped-flow apparatus using the iron (III)--thiocyanate reaction. The software can readily be used to retrieve that data from the stopped-flow apparatus using one probe to measure the voltage and a second probe to trigger the data…

Describes two simulations, written for Apple II microcomputers, focusing on scientific methodology. The first is based on the tendency of colloidal iron in high concentrations to stick to fish gills and cause breathing difficulties. The second, modeled after the dioxin controversy, examines a hypothetical chemical thought to cause cancer. (JN)

Describes a course that weaves the learning of how to use the chemical literature with a discussion of the chemistry of the elements. The use of computer programs and games enables students to explore trends of properties among the elements. (DDR)
