Presents a new approach for the determination of the temperature coefficient of resistance of a resistor and a thermistor. Advantages include teaching students how to linearize data in order to utilize least-squares techniques, continuously taking data over desired temperature range, using up-to-date data-acquisition techniques, teaching the use…

Describes two spreadsheets for producing acid-base titration curves, one uses relatively simple cell formulae that can be written into the spreadsheet by inexperienced students and the second uses more complex formulae that are best written by the teacher. (JRH)

Provides an activity which measures the heat transfer through an insulated cylindrical tank, allowing the student to gain a better knowledge of both the physics involved and the working of spreadsheets. Provides both a spreadsheet solution and a maximum-minimum method of solution for the problem. (MVL)

Described are some commonly encountered chemistry experiments that have been modified for computerized data acquisition. Included are exercises in radioactivity, titration, calorimetry, kinetics, and electrochemistry. Software considerations and laboratory procedures are discussed. (CW)

Describes a two-week lesson on electric fields that combined lecture, interactive video, lab experimentation, computer spread sheets, and computer-assisted-graphing. (PR)
