This item is an interactive set of Flash images produced with infrared photography. Infrared is primarily heat radiation and is emitted by anything with a temperature -- even cold objects. On this web page, students will see infrared images of a cup of hot coffee, Old Faithful geyser, ice cubes, cold-blooded and warm-blooded animals, hot springs, and more. The photographic technique allows them to "see" the heat radiated by each object as well as the conduction of heat from one object to another. Included is a background essay and questions for classroom discussion.
Teachers' Domain is an NSF-funded pathway of the National Science Digital Library (NSDL). It is a growing collection of more than 1,000 free educational resources compiled by researchers and experienced teachers to promote the use of digital resources in the classroom.
Please note that this resource requires Flash.
This resource is part of 2 Physics Front Topical Units.
Topic: Nature and Behavior of Light
Unit Title: Electromagnetic Radiation and the Spectrum
All objects with a non-zero temperature will emit infrared radiation, but we cannot see it with our eyes. This excellent collection of images produced with infrared photography allows students to "see" temperature differences and variations in heat intensity. They will be looking at a hot cup of coffee, warm-blooded and cold-blooded animals, ice cubes, and hot springs. For an inquiry-based lab to extend this exploration, see "Science NetLinks: The Herschel Experiment" in Lesson Plans above.Link to Unit:
Topic: Heat and Temperature
Unit Title: Teaching about Heat and Thermal Energy
All objects emit infrared radiation, but human eyes cannot see these wavelengths. Infrared is essentially heat radiation and is emitted by anything with a temperature. This tutorial, produced with infrared photography, lets students "see" infrared images of a cup of hot coffee, Old Faithful geyser, ice cubes, cold and warm-blooded animals, hot springs, and more.Link to Unit:
