Resource	Grade Level	Media Type
Antarctica: A Challenging Work Day What happens when the ground under your feet is ice and it's moving? This video segment adapted from NOVA features some of the dangers faced by scientists conducting research in Antarctica.	3-12	QuickTime Video
Antarctic Ice Movement: Part I This video segment adapted from NOVA explains why ice sheets move. To find out how fast they move, scientists carve a tunnel through a glacier.	6-12	QuickTime Video
Antarctic Ice Movement: Part II Within Antarctic ice sheets are fast-moving streams of ice. This video segment adapted from NOVA hypothesizes about how ice streams are the result of warming at the end of the last ice age.	6-12	QuickTime Video
Cave Formation: Biogeochemical Cycles This video segment adapted from NOVA chronicles the discoveries that led to a radical new theory in which living organisms, not just geological processes, play an active role in cave formation.	6-12	QuickTime Video
Cave Formation: Kane Cave This video segment adapted from NOVA describes a simple experiment that confirmed the idea that microbes can accelerate the biogeochemical process of cave formation.	6-12	QuickTime Video
Caves: Extreme Conditions for Life This video segment adapted from NOVA raises the provocative idea that if life can exist in the most extreme environments on Earth — such as in dark, toxic caves — then perhaps living things can also survive in harsh environments on other planets.	6-12	QuickTime Video
Chasing Tornadoes In this video segment adapted from NOVA, scientists are on the hunt for tornadoes. Using Doppler radar, they gather data in the hopes of solving the mystery of how tornadoes form.	6-12	QuickTime Video
Collecting Data Below the Earth's Surface This video segment adapted from Discovering Women demonstrates how scientists use sound waves to collect data about the structure of Earth's crust.	6-12	QuickTime Video
Dating Lava Flows on Mauna Loa Volcano, Hawaiʻi In this video segment adapted from NOVA, scientists search for carbonized remains of plants preserved in lava flows to find out how long it has taken rain forests on Hawaiʻi to regenerate after a volcanic eruption.	3-12	QuickTime Video
Earthquakes: The Prehistoric Record In this video segment adapted from NOVA, a geologist digs a trench along the San Andreas Fault to reveal three thousand years of earthquake history. Information from the layers of sediment may help geologists to predict earthquakes.	3-12	QuickTime Video
Flood: Farming and Erosion In this video segment adapted from NOVA, scientists investigate how farming along the Mississippi River impacts floods and what can be done about it.	3-12	QuickTime Video
Global Warming: Carbon Dioxide and the Greenhouse Effect This video segment adapted from NOVA/FRONTLINE demonstrates the physical property of carbon dioxide that causes the greenhouse effect.	6-12	QuickTime Video
The Great Flood of 1993 In this video segment adapted from NOVA, a meteorologist explains how an unusual weather pattern led to one of the most devastating floods of this century.	6-12	QuickTime Video
A Hole in the Sky This video segment adapted from Interactive NOVA profiles two scientists who were surprised in 1984 to discover a hole in our atmosphere's ozone layer as big as the United States.	6-12	QuickTime Video
How Do Avalanches Form? In this video segment adapted from NOVA, dramatic footage of avalanches and animations of ice crystals illustrate how a layer of weakly-bonded snow can contribute to a devastating avalanche.	6-12	QuickTime Video
How Do Tornadoes Form? In this video segment adapted from NOVA, scientists use computer simulations to explore the question of how supercell thunderstorms produce tornadoes.	6-12	QuickTime Video
Hurricanes: New Tools for Predicting This video segment adapted from NOVA scienceNOW features new advances in predicting the intensity of hurricanes.	6-12	QuickTime Video
Lava Sampling on Kilauea Volcano, Hawaiʻi In this video segment adapted from NOVA, scientist Mike Garcia draws lava samples at the foot of the active Kilauea volcano to see if it is related to its neighboring volcano, Mauna Loa.	6-12	QuickTime Video
Mount Pinatubo: Predicting a Volcanic Eruption This video segment adapted from NOVA relates the dramatic story of vulcanologists trying to predict the timing of the cataclysmic eruption of Mount Pinatubo in the Philippines.	6-12	QuickTime Video
Plate Tectonics: Lake Mead, Nevada Using animations to illustrate the theory of plate tectonics, this video segment adapted from Discovering Women takes you to Lake Mead, Nevada, to see visual evidence of how plate movement has been stretching the North American continent.	6-12	QuickTime Video
Polar Bears and Climate Change In this video from the World Wildlife Fund, learn how rising temperatures in the southern Arctic could lead to polar bear extinction.	6-12	QuickTime Video
Taking the Earth's Temperature This video segment from FRONTLINE/NOVA: "What's Up with the Weather?" depicts research efforts to record Earth's past and present temperatures shifts.	9-12	QuickTime Video
When Did the First Americans Arrive? In this video segment adapted from NOVA, recent archeological evidence leads scientists to revise existing theories about human migrations into the Americas around the time of the last ice age.	6-12	QuickTime Video
