Data-logging
Recently the Education Department has added data-loggers into the standard equipment list for secondary schools (Science Education KLA, 2000). Data-logging is a trend in practical activities in science education. Its major advantages are the high sensitivity for measurement of very small changes and the ability to monitor changes over a very short or a very long period of time. It can record and store data of one or more parameters. The variations of several parameters can be shown on the same graph for comparison of trends and analysis for inter-relationship. As the recording and the presentation of data are automatic, time can be saved for repeating the experiment with different settings and parameters. That is, it creates a favorable condition for conducting more scientific investigations.
