Hiding heat radiation
Students will answer questions about the Science News article “Coating provides infrared camouflage,” which explores the physics and potential technological applications of a material.
Educator Guide: Coating Provides Infrared Camouflage
When heated from about 100° to 140° Celsius (left to right), a normal material (top) radiates more brightly, and an infrared camera registers a higher temperature (brighter colors). But a special coating (bottom) fools the camera into detecting little temperature change.

About this guide
This guide, based on the Science News article “Coating provides infrared camouflage,” asks students to explore the physics and potential technological applications of a material, discuss the various types of electromagnetic radiation, analyze infrared images and research how infrared imaging is used across a range of fields.
This Guide Includes:
Exploring electromagnetic radiation
Students will watch a NASA video about the electromagnetic spectrum to learn about properties of the various types of radiation. Then, students will explore and discuss technologies that use specific types of electromagnetic radiation.
Seeing in infrared
In this activity, students will analyze infrared images and then explore how infrared imaging is used across a range of fields of work. Skills include researching, evaluating, synthesizing and presenting information.
