Infrared Energy

Explore infrared energy and how NASA detects it to study our Earth's systems more completely in this video adapted from NASA.

Infrared Gallery

How would your world look if you saw heat instead of light? In this interactive resource produced for Teachers' Domain, see what familiar objects look like through an infrared camera and watch infrared videos of geysers, mudpots, and hot springs.

Infrared: More Than Your Eyes Can See

In this video segment adapted from NASA, astronomer Michelle Thaller introduces the world of infrared light and demonstrates how infrared cameras allow us to see more than what the naked eye can perceive.

Inside a Solar Cell

This interactive activity adapted from NOVA Online features animations that illustrate the components of a typical photovoltaic cell and how it converts solar energy into electricity.

Inspector Detector Challenge

In this video from Design Squad Nation, kids design and build magnetic-field detectors and use them to find hidden magnets. They also learn how NASA uses magnetometers to learn what is going on inside a planet or moon.
