Material Detail

This is a lesson about infrared radiation. Learners will investigate invisible forms of light as they conduct William Herschel�s experiment and subsequent discovery of infrared radiation. They will construct a device to measure the presence of infrared radiation in sunlight, explain that visible light is only part of the electromagnetic spectrum of radiation emitted by the Sun, follow the path taken by Herschel through scientific discovery, explain why we would want to use infrared radiation to study Mercury and other planets, and explain how excess infrared radiation is a concern for the MESSENGER mission. This is activity 1 of 4 at the Grade 5-8 band of "Staying Cool."
