This set of three activities will enable students to understand the electromagnetic spectrum and observe infrared radiation through the modification of a cheap webcam. It will enable discussion of how infrared radiation can be used to obtain information that is not accessible using visible light. Students will also analyse satellite images to understand why it is useful to “see” in infrared light. With the true colour and false colour satellite images, students will understand how infrared light can be used to monitor the health of vegetation.
