When we discuss infrared and infrared astronomy we refer to infrared as being primarily thermal radiation or radiation due to heat. In this module we introduce the concepts of heat and temperature, heat transfer and detection. We also introduce several examples of what we can learn by detecting heat and measuring temperature and include links to related classroom lesson plans and activities.

What is Heat and What Causes It? What is Temperature How Does Temperature Differ From Heat How Does Heat Travel? How Do We Detect Heat?

How Do We Measure Temperature? What Can We Learn From Heat Radiation? Additional Classroom Activities and Experiments National Science Standards Grades K-4 National Science Standards Grades 5-8 National Science Standards Grades 9-12
