Learners are expected to conduct investigations and are often introduced to modern scientific tools. Data logging is used as a tool to automatically and accurately record data over time using sensors (e.g., temperature, light) connected to a computer or specialized device. This replaces manual recording and allows for real-time graphical analysis of results.

Data logging is studied as a method of direct data capture where sensors and data loggers are used to automatically collect data from the environment and input it into a computer system for storage and processing (e.g., monitoring weather conditions, traffic flow, or environmental systems).

The use of data logging equipment to conduct and enhance practical experiments. It allows for the precise collection of data, such as motion (velocity, acceleration) or changes in temperature/pH during reactions, improving the accuracy and efficiency of complex practical tasks.
