This is an interactive image set and video set depicting 11 objects with both traditional photography and infrared photography. The infrared images show cold objects in the purple-to-black color range, while hotter objects show up as yellow-to-red. The resource can serve two purposes: 1) A clear visual display of thermal energy being transferred from a hotter to a cooler object; and 2) A way to “see” temperature differences in a way that cannot be detected with human vision. The video objects include the Old Faithful Geyser, mudspots, and hot springs. The images include a melting ice cube, cups with hot and cold drinks, a cup of hot coffee, a shoe with the foot just taken out, and a warm-blooded animal (human) holding a cold-blooded reptile.
