Data-logger allows the investigation of changes in experimental processes. Using data-logger to monitor biological changes brings a new dimension to biology teaching and learning. The hardware, together with a computer, can record and store the data of one of more parameters. The variations of several parameters can be shown on the same graph for comparison of trends and analysis for inter-relationships. This demonstration session showed several data-logging experiments about energy content of foods, glycolysis, photosynthesis and transpiration. Specifications of the hardware requirement will be explained. Comparisons with similar experiments using traditional apparatus will be also discussed.
