Subtopic: Energy in the Earth System

. Change grade range

Resource	Grade Level	Media Type
Deep-Sea Vents and Life's Origins Deep-sea vents are home to life forms that do not rely on the Sun's energy. They depend instead on energy from volcanoes on the ocean floor. This video segment adapted from NOVA hypothesizes that life on Earth may have begun in this extreme environment.	3-12	QuickTime Video
Earth as a System This visualization adapted from NASA maps progressive global changes onto a rotating globe. Earth's atmosphere, hydrosphere, geosphere, and biosphere are shown to be dynamic and interconnected.	6-12	QuickTime Video
Earth System: Ice and Global Warming This video segment adapted from NASA's Goddard Space Flight Center explains ice's role in the Earth system, highlighting the delicate balance that could be upset with a continued rise in temperature due to climate change.	6-12	QuickTime Video
Energy Sources This video segment produced for Teachers' Domain illustrates a variety of energy sources used to generate electricity, some of which are in use and some of which are under exploration.	3-12	QuickTime Video
Examine Global Surface Currents This visualization from McDougal Littell/TERC visualizes the relationship between global wind directions and the direction of ocean surface currents.	6-12	Flash Interactive
Global Trends Quiz In this interactive quiz from NOVA, take the Environmental Challenge and test your knowledge of human impact on the world's natural resources and climate.	3-12	Flash Interactive
Global Warming: The Physics of the Greenhouse Effect This video segment adapted from NOVA/FRONTLINE examines the greenhouse effect, its role in keeping Earth habitable, and the industrial changes that have led to an increase in the planet's average temperature.	6-12	QuickTime Video
The Grand Canyon: Ancient Mountains This video segment adapted from NOVA features the twisted and melted forms of the Grand Canyon's oldest rocks, the 1.7-billion-year-old Vishnu Schist.	6-12	QuickTime Video
Great Ocean Conveyor Belt: Part I This image from GRID-Arendal depicts the major circulation pattern of the ocean, illustrating interactions between temperature, salinity, and depth.	9-12	GIF Image
Great Ocean Conveyor Belt: Part II A substantial increase in freshwater running into the northern Atlantic Ocean could dramatically affect climate and global ocean currents. This audio segment from National Public Radio presents viewpoints from scientists studying changes in ocean circulation.	6-12	QuickTime Audio
Infrared Gallery How would your world look if you saw heat instead of light? In this interactive resource produced for Teachers' Domain, see what familiar objects look like through an infrared camera and watch infrared videos of geysers, mudpots, and hot springs.	3-12	Flash Interactive
Infrared: More Than Your Eyes Can See In this video segment adapted from NASA, astronomer Michelle Thaller introduces the world of infrared light and demonstrates how infrared cameras allow us to see more than what the naked eye can perceive.	3-12	QuickTime Video
Ocean Temperatures and Climate Patterns This animation from The New Media Studio illustrates how the atmosphere and ocean together shape wind, current, and rainfall patterns in the tropical Pacific.	6-12	QuickTime Video
Solar Wind's Effect on Earth 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.	3-12	QuickTime Video
