Pbs Learning Media: Water Vapor Circulation on Earth

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...

How did life first arise on earth? There are many theories and scientists Stanely Miller and Harold Urey set out to recreate the environment of early earth in order to find some answers. Watch this video from NOVA to see the results of...

This video segment adapted from NASA describes solar storms and their effects on Earth. Animations of coronal mass ejections and solar cycles help explain what we know, and what we can predict, about solar activity. [4:44]

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...

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]

Students learn about the giant impact hypothesis for the Moon's formation, and how the Apollo Moon rocks have contributed to scientists' understanding of the Moon.

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...

Students learn how various kinds of data and information can be gathered to create a biodiversity timeline that serves as evidence of changes in a population of a species.

When light strikes an object it can cause reflection or absorption depending on the wavelength of the light and the property of the material that makes up the object. Watch this whiteboard animation for a full explanation and to find out...
