Thermal cameras have shown to have utility in secondary school classrooms and undergraduate courses. In this paper, the author argues for their potential in the primary school classroom and presents a range of activities that can be undertaken with thermal cameras (or supplied images). With limited access in mind, the activities in this paper have been designed to be practiced in 'demonstration mode' with only one thermal camera or even by using a bank of existing photographs made available to teachers and students. Activities can be modified for individual use or for use in small groups if students have one-to-one access to the cameras.
