Pbs Learning Media: The Electromagnetic Spectrum: Nasa

This video segment adapted from FRONTLINE introduces the electromagnetic spectrum and explains how the various types of electromagnetic waves are distinguished by the amount of energy each wave carries.

Scientists study ice sheets because they influence weather and climate, playing a role in atmospheric and ocean circulation. Ice sheets can also have huge impacts on global sea levels because they store so much water. Explore this...

This video segment adapted from NASA's Goddard Space Flight Center explains how and where hurricanes develop. Learn how El Nino events alter the course of atmospheric circulation. Includes background reading material and discussion...

Observe how the sea ice changed in 2016 after it reached its maximum extent in late March and proceeded through the melt season in this video from NASA. Scientists study sea ice because it influences global climate. Resouces include...

Examine this visualization by NASA to understand how the warming of the Arctic region has caused the sea ice extent to decline by 40%, thereby throwing our earth's energy budget off balance. Extensive resources included are teaching...

The Arctic plays an important role in regulating Earth's climate. The region reflects much of the Sun's energy and helps keep the planet cool. Data collected by NASA have revealed that sea ice in the Arctic has steadily declined over the...

Everything in our environment is interconnected. A change in one area causes a change in another area. Nowhere is this more evident than in our climate. NASA created a theoretical planet called "Daisy World" to show the complex system of...

This video segment adapted from NASA's Goddard Space Flight Center details some of El Nino's far-reaching effects on both marine life and humans. [2:44]

Learn about thermal energy, also known as heat or heat energy, and the ways in which it can move from one object to another,
