Using data-logger is a trend in experimentation in science education. Its advantages are the relatively higher sensitivity for the measurement of very small changes in any physical quantity and the ability to monitor changes over a very short or a very long period of time. High sensitivity means that the duration of an experiment can be shortened, as we do not need to wait for significant changes. On adopting a data-logging system, the experimenter can accurately monitor fast changes without missing any data points (because of the high sampling rate of the hardware) and can save a lot of labor and time from monitoring slow changes because the computer can collect and store data automatically. However, these data collecting abilities are sometimes over-emphasized while the applications of data-logger in developing students’ investigation skills is overlooked. This paper uses the topic “Solubility” as an exemplary activity to show how to carry out a data-logging investigation activity rather then just simply collecting data.
