This video adapted from the Valdez Museum & Historical Archive, explores what happened during the Great Alaska Earthquake of 1964 through original footage, first-person accounts, and animations illustrating plate tectonics.
This video segment adapted from First Light explains why the highest peak in the Pacific, Mauna Kea, is an ideal site for astronomical observations. Featured are new telescope technologies that allow astronomers to explore the universe in more depth.
This segment from Swift: Eyes through Time traces the history military officers and engineers discovering a strange phenomenon in the sky that astronomers now know are gamma-ray bursts.
In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.
In this video segment adapted from ZOOM, two cast members demonstrate what happens when vinegar is added to baking soda inside a container. The resulting chemical reaction produces enough carbon dioxide to launch their paper rocket skyward.
Recommended for: Grades K-5
A car propelled by the reaction between lemon juice and baking soda has more in common with rockets and jet aircraft than one might think. In this video segment adapted from ZOOM, two cast members demonstrate the power of rocket-propelled vehicles and how to exploit the force produced by the carbon dioxide gas. Grades 3-8.
It would seem that bottles of lemon juice and rockets have only their basic shape in common. However, as two cast members from ZOOM demonstrate in this adapted video segment, when baking soda is added to the mix, a plastic bottle can act very much like a real rocket. Grades 3-8.
Finches on the Galapagos Islands have evolved to exploit almost every possible niche. This diagram shows the range of food sources available on the island and the different beak shapes adapted to exploit each of them.
Hear about how respect for Earth can help us attain a more sustainable lifestyle in the face of climate change in this video segment adapted from United Tribes Technical College.
Our brains control every movement we make. Most of us take for granted our ability to pick up a cup or change the television station. However, for people who have lost a limb or become paralyzed, the inability to do these things means a loss of freedom and independence. This video segment from Greater Boston describes how neuroscientists and bioengineers have teamed up to create a system that allows people who have lost motor functions to control electronic devices through their thoughts alone. Grades 6-12
Discusses the economics of slavery in South Carolina and its importance to the profitable growing of rice. It continues with ways the slaves were controlled and punished in South Carolina and Georgia. Click on Teacher's Guide for teacher resources.
Do you need proof that driving is a dangerous activity? More Americans have died in car crashes over the past 100 years than in all the wars the U.S. has ever fought combined. More than 40,000 Americans die each year on the nation's highways, most as the result of high-speed collisions. In this video segment adapted from NOVA, learn how engineers developed the air bag, an important automobile-safety device now found in most cars.
Recommended for: Grades 3-12
In this video segment adapted from ZOOM, cast members make their own hovercraft and demonstrate how the air leaking out of a balloon can make a plastic plate hover above a table.
This video from First Alaskans Institute spotlights the Alaska Native community of St. Paul and its hands-on commitment to care for the land and animals on which it depends.
In this video adapted from Storyknife Productions, Alaska Native pilots share how they use traditional knowledge to read the landscape and predict the weather.
In this video adapted from KUAC-TV and the Geophysical Institute at the University of Alaska, Fairbanks, Alaska Native students contribute to research on how their environment is changing as a result of global warming.
