A 9.0 magnitude earthquake rocks the ocean floor about eighty miles off the coast of Japan. This disturbance causes a transfer of energy from the seafloor to the ocean, which generated a series of ocean waves known as a tsunami. Within 20 minutes, the waves struck the Japanese coastline, and other nations go on high alert as the tsunami spreads throughout the Pacific Ocean. Part of the "Danger Zone" series.

Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko learns about water tables and how streams develop. During the dry season, the river level drops and the remaining water turns to mud. He can't swim or drink the water. A man with a strange stick points the stick to the ground, and when Moko digs down there, water gushes out! Moko learns that even if no rain falls, Mother Earth could still be generous if you know the right way to ask her.
Since the last ice age, plants in the Alaskan Arctic have been taking carbon out of the atmosphere and locking it away in the soil. But now, the permafrost is starting to thaw. That means all those microbes are about to find themselves at an all-you-can-eat carbon buffet. With support from the National Science Foundation, ecologist Matthew Wallenstein and a team from Colorado State University have come to the Toolik Field Station, deep inside the Arctic Circle, to drill soil cores for study. The researchers are trying to find out more about how microbes in the soil are cycling carbon from the Earth to the atmosphere. Part of the National Science Foundation Series “Science Nation.”
Bay Mouth Bar holds what is reputed to be the largest diversity of predatory snails in the world. Dr. David Kimbro is investigating how top predators in this group of seagrass beds affect the system as a whole, which in turn affects local fisheries. Part of the series "In The Grass, On The Reef."
The geologic processes of mountain building, seafloor spreading and volcanoes are a few examples of the power of plate tectonics. Footage filmed on-location in Iceland, the Canadian Rockies, and Crater Lake help viewers understand the theory of plate tectonics. Colorful animations illustrate the movement of tectonic plates and the role this plays in the development of geologic features. Other terminology includes: theory of continental drift, mid-ocean ridge, plate boundaries, subduction, convergent boundary, and divergent boundary.
In the Pacific Northwest, people are stripping moss for the horticultural trade at such an alarming rate that it's now illegal to harvest it. Ecologist Nalini Nadkarni knows that moss is a key component to the eco-system of the region, which makes it important to study. But this globe-trotting scientist at The Evergreen State College needed a lot of help recording research data from some folks who have much more time than she does. Where better to find potential research assistants with lots of time on their hands than the nearby medium security Cedar Creek Corrections Center? With support from the National Science Foundation, Nadkarni’s idea has been so successful that now the prisoners are starting bee keeping and composting programs, in addition to growing and recording data about moss.
In the last few years, the Red Planet has yielded up many new clues that life may have once existed there...and may even exist there today. There is now proof that water once flowed on the surface, that Mars once had lakes, and that the frozen poles are mostly water. Mars has snow--an aurora--and lightning generated by dust storms. Most intriguing of all are the seasonal plumes of methane that just may point to bacteria living below the surface.
A chart of exponential growth shows that some things change faster over time. Back in 1798, Thomas Malthus noticed that not everything grows this way. This caused people to worry, and they were sure it would lead to massive death, starvation, and famine. However, the Green Revolution kept this from happening, and scientists are currently working to produce enough food for the current exploding population. Part of the “It’s Okay to Be Smart” series.
When the water along Rhode Island’s Narragansett Bay is thick and green, it may be a bad day for a swim, but it’s an excellent day for University of Rhode Island marine ecologist Carol Thornber. Thornber and her team are conducting a long-term study of the impacts of climate change on macroalgae, or seaweed, and algal blooms. She is investigating how the blooms affect fish stocks and oyster beds as well as how nutrients in the water from sewage treatment and agricultural runoff can feed the blooms and make them larger. Part of the "Science Nation" series.
Why is there such an alarming increase in the number of children with food allergies? More than three times as many children have food allergies now than twenty years ago. And one out of every three children is now allergic to something, be it food, animals, or plants. In searching for a fix, scientists are upending the conventional wisdom about what causes allergies and how to deal with them.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. As Tim delivers the last of the season's honey to his grandfather's customers, the jars get broken. Tim's solution is simple: get more honey from some bees. But Ms. Frizzle sweetens the idea by turning her class into bees and showing them a beehive up close and personal.
The ancient city of Rome wasn't built in a day, but now that city, along with all its famous landmarks, can be digitized in just a matter of hours. A new computer program under development at the University of Washington in Seattle combs through hundreds of thousands of tourist photos on Flickr and other photo sharing sites and reconstructs the city – pixel by pixel. Now, viewers can fly around many of Rome's famous landmarks on their computer in far more detail than they'd ever be able to on current virtual map programs such as Google Earth. The new technique may one day create online maps that offer viewers a virtual-reality experience. The software could build cities for video games automatically, instead of doing so by hand.
What do wild animals do when we're not around? Find out with National Geographic's Crittercam. Safely worn by wildlife, Crittercams capture video, sound, and other information, giving students rare views of the private lives of animals. Crittercams help to solve scientific mysteries by providing an animal's eye view. And what scientists learn from Crittercams helps them protect the very animals that wear them. Join the Crittercam team in Cape Washington as they deploy special cameras to reveal how emperor penguins travel vast distances to feed -- and then run a dangerous gauntlet back to their chicks.
Dark matter is a scientific mystery. But physicists like Dan McKinsey theorize it must exist because without it, the universe would look quite different. With support from the National Science Foundation, McKinsey and a team of scientists from across the U.S. and Europe are hard at work on the Large Underground Xenon, or LUX, experiment. Nearly a mile straight down an old mine shaft at the Sanford Underground Research Facility in Lead, South Dakota, the team searches for the existence of one possible type of dark matter called weakly interacting massive particles, or WIMPs. Part of the National Science Foundation Series “Science Nation.”
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, night falls and Moko, having followed the footprints in the snow, reaches the seemingly uninhabited village. He notices a young boy by a shrub who is cutting firewood. He introduces himself as Alarick and invites Moko into his home. Along the way, they hear a great rumbling sound that startles them, like the breath of a monster. Moko wants to go to the source of the noise, thinking it is the reason for the villagers' hiding. Alarick then leads him to the back of the village where he shows him a geyser and a pool of hot water. Moko thinks that Alarick must know a great deal of secrets about this new land and decides to stay a while, the end of the world can wait for now.
In this episode, host Steve Backshall conducts an investigation into what makes the Okavango such a diverse place. The Okavango Delta is a vast inland river delta in northern Botswana. It's known for its sprawling grassy plains, which flood seasonally, becoming a lush animal habitat. Part of the "Nature's Microworlds" series.
Scientist William Rowan is renowned for his research on the dark-eyed junco. Before Rowan, it was unknown what environmental cues animals used to time the seasonal changes in their biology. Through a groundbreaking experiment with the junco, Rowan discovered the physiological reaction of organisms to the length of day or night. Shot as an historical re-enactment, this segment provides a glimpse into the history and human dimensions of scientific research and reveals one of the first studies that made juncos well-known to biologists. Part of Ordinary Extraordinary Junco (Chapter 1).
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko is woken by the sound of singing coming from the other end of the beach. It is Mei-Lei. As they are walking towards her village, they feel a terrible rumble and see black smoke coming from the mountain. Moko thinks this is his fault, that he has trespassed in the forbidden forest, and wants to apologize. They arrive at the edge of an enormous chasm, a veritable fire pit. To prevent the volcano from erupting, Moko offers it a beautiful seashell, as Mei-Lei's ancestors did. The mountain's rumbling stops and Moko is proud to have learned its language.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. It's the night of the rock lovers' annual Granite Awards, and Arnold is about to become the first kid ever to win the coveted Rocky Award. He's so excited; all he's been able to eat for weeks are "Seaweedies.” When he arrives for the big event, he’s nervous and orange. Once the class determines that the orange isn't on Arnold's skin, they shrink down to explore what's underneath. They discover that his whole body is made of living cells, and they're all orange.
