How does NASA "see" thermal radiation? This video, adapted from NASA, explores what infrared energy is and how NASA detects it to study our Earth's systems more completely. The video also includes a look at the experiment Sir William Herschel conducted that led to the discovery of infrared.
This media asset was adapted from "Earth Science Week 2010 - Infrared Energy" NASA Goddard Space Flight Center.
Classroom Activity: Infrared Morse Code
Students send messages using the invisible infrared signals emitted by TV remotes.
Materials needed: several TV remotes, cell phones with cameras, and Morse Code charts.
Note: For classrooms with access to an infrared camera or a web camera that has had its infrared filters removed, activities can include viewing a range of objects through the infrared set-up, comparing those images to visible light images, and/or creating infrared images as prompts for discussion and interpretation.
