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
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.
In this video adapted from Alaska Sea Grant, discover why multiple tsunamis resulted from the Great Alaska Earthquake of 1964.
In this Evolution Web feature, test your skills at judging who's who on the tree of life while you learn about the tools and methods of cladistics.
These images from the Smithsonian Institution depict Nancy Knowlton's work with snapping shrimp in Panama. Knowlton found that the closing of the isthmus -- dividing the Pacific Ocean from the Caribbean -- resulted in new species of shrimp.
This video segment from the Secret of Life School Video: "Genetic Medicine: Tinkering with Our Genes" explores the potential for gene therapy to cure diseases like Alzheimer's.
This annotated slideshow adapted from KET's Electronic Field Trip to the Forest illustrates how blight decimated the American chestnut tree and the methods scientists use to identify and pollinate the remaining trees to create blight-resistant trees.
Find out how angles and symmetry come into play in the game of pool in this video adapted from Annenberg Learner’s Learning Math: Measurement.
It takes a thick skin to withstand the hardships that life has to offer. This collection of images shows a variety of animals, each with a slightly different type of protective covering.
In this activity, students learn how an animal's sense of hearing is adapted to -- as well as affected by -- its environment. They begin by exploring how a shark's senses enable it to be an efficient predator. Students then compare a shark's senses to those of a land animal of their choice, and discover how each animal's senses are adapted to its particular environment. Next, they focus on the sense of hearing, and a common cause of hearing loss: continual exposure to loud noises. Students learn how a change in the way that an Arctic community hunts -- using rifles instead of harpoons -- has caused widespread hearing loss. Finally, students research noise levels in their environment and conduct a public awareness campaign about noise pollution and the associated hearing loss.
Learn about the structure and function of living organisms by drawing an imaginary animal in the Take the Stage game show, ANIMAL SURVIVAL! Viewers become contestants on a game show and are challenged to draw an imaginary animal that could live and survive in either the desert, ocean, or the arctic tundra. When drawing the imaginary animal, the contestants write out two distinct structures and a function for each of the structures that help it survive. Learning Objective: Compare the structures and functions of different species that help them live and survive in a specific environment.
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.
What would happen if a portion of the Antarctic Ice Sheet were to melt? This video segment adapted from NOVA uses animations to show the effect of a 6-meter sea-level rise on coastal cities across the world.
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.
This video segment adapted from NOVA uses microwave images to reveal how sea ice doubles the size of Antarctica each winter. Rare footage shows how sea ice crushed the famous ship Endurance in 1914.
This video segment adapted from Building Big illustrates the strength of the arch in bridge design and construction.
This video segment from Wild Europe: "Wild Arctic" explores the struggle for survival in one of Earth's most extreme environments.
