After putting one sensor in the hot water cup and the other one in cold water cup, students could observe the comparative change in the temperature from the data logger’s computer interface. If they take temperature readings through an alcoholic thermometer, they have to be very alert in taking the readings of both water cups at regular intervals. Using data logger, it was easier to measure minute changes in temperature and students were free from the hassle of taking temperature readings manually.
Data logger helped students to better understand the procedure of scientific investigation. It handled the task of measuring temperature automatically and therefore students could use their free time to predict and compare the changes in temperature. Observing the graph created by the computer interface of data logger helped students in shaping their understanding about why temperature of the hot and cold water was changing and discussing the reasons behind it.
Data logger is a user friendly tool that helps students observe, compare and analyze minute changes in temperature with the help of a graph. Connected to a computer, it can be used to display the results as they happen in the form of a graph. Thus data logger decreases the anxiety among the students about taking accurate temperature reading at regular intervals and creating graphs. Using the data logger, the issue of students losing their concentration and forgetting to take the temperature reading at the right time will not arise. Data logger also develops higher order thinking skills among students i.e., analysis, evaluation and synthesis.
