Pbs Learning Media: Solar Wind's Effect on Earth

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]

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...

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 simulation from the National Center for Atmospheric Research portrays annual patterns in water vapor and precipitation across the globe, illustrating general circulation patterns as well as seasonal and regional variation. [4:52]

ZOOM cast members use a homemade solar still to mimic the water cycle, separating pure water from a saltwater mixture. [3:34]

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...

The enormity of the solar system can sometimes be too big to imagine. A scale model can help us visualize the size in an easy to understand way. Watch as scientists build a model of the solar system in a dessert just 7 miles in diameter!...

This video segment adapted from NOVA/FRONTLINE demonstrates the physical property of carbon dioxide that causes the greenhouse effect. Includes background reading and discussion questions. [2:26]

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.

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...
