Primary teacher and ICT co-ordinator Chris Thomas explains that a data logger is a device that can record - among other things - light, temperature and sound. He demonstrates the main features of a data logger and shows how to turn it on to obtain live readings and how to record and save data and then transfer it to a computer via a cable plugged in to the computer's USB socket. Chris uses the data logger to take readings of the temperature of a cup of tea as it cools and shows how graphs based on the readings can instantly be created using the data handling software.
