Thermal cameras offer real-time visual access to otherwise invisible thermal phenomena, which are
conceptually demanding for learners during traditional teaching. We present three studies of
students? conduction of laboratory activities that employ thermal cameras to teach challenging
thermal concepts in grades 4, 7 and 10?12. Visualization of heat-related phenomena in combination
with predict-observe-explain experiments offers students and teachers a pedagogically powerful means
for unveiling abstract yet fundamental physics concepts.
