Exploring Earth: Temperature Mapping

In this activity, learners model the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

DESCRIPTION

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures. IR technology, like the IR thermometer in this activity, uses the infrared light emitted by an object to measure its temperature remotely (without having to touch it!) By taking a series of measurements over an area, a scientist can create a visual representation of the surface temperatures (like a weather map for surface temperatures rather than air temperatures.)

OBJECTIVES

BIG IDEA

Earth is a constantly changing and dynamic system.

LEARNING GOALS

    • Different types of land cover on Earth absorb or reflect energy from the Sun in different ways. 
    • NASA scientists study land cover to understand and predict how Earth's climate is changing.
