Includes the complete listing for a computer program which draws the best curve to fit calibration data obtained from a set of five standard solutions. (DH)

Describes the methods and materials used to obtain satellite pictures from weather satellites. Discusses possible physics lessons which can be done using this equipment including orbital mechanics, and how the satellite works. (CW)

Discusses a new computer modelling system and compares a teaching strategy that uses computers to explore exponential decay with a teaching method employing the Cellular Modelling System in which the monitoring of a real experiment and the development of a model representing the experiment are done at the same time. (CW)

Described is a means of logging data from remote sensors in data files and then transferring the data to a spreadsheet for processing. The presentation of the data in tabular or graphical form is discussed. An example using temperature data from a model house is provided. (Author/CW)
