When Geologist Jeff Donnelly of the Woods Hole Oceanographic Institution (WHOI) hunts for hurricanes, he does it safely at ground level, or just slightly below. He is even able to do it without having to encounter so much as a drop of rain or a gust of wind. With funding from the National Science Foundation, Donnelly leads a team that studies long term global hurricane patterns. They’ve unearthed some interesting findings about past hurricane activity which might provide a hint about what to expect in the future.

Parakeet is talking and gets hit by Amanda. A little hole opens and Amanda begins to wonder if Parakeet is a boy or girl. The first panelist is the rabbit, since she can tell if Parakeet is a boy or girl due to her experience on the topic, but all are surprised to find out the panelist is a male rabbit. The fleas show a documentary on how the human male species have pushed females into the background. The celebrity guests, Hill and Billary Clinton, share a story from school that sets an example for all those attending the show.
Earth's moon was probably formed when a body the size of Mars collided twice with the planet. The moon is steadily receding into space; eventually, due to the loss of this lunar regulator, Earth will start to wobble, creating climatic chaos. Eclipses can be also seen often when the sun obscures the moon or vice versa. Another light show, the Aurora, occurs when electrified particles from the solar wind interact with Earth's upper atmosphere and is visible particularly in the Polar Regions.
In 1936, Ruth Harkness, a dressmaker from New York, set off to China in search of the rare, elusive giant panda. Her goal was to bring one back alive to New York. She wanted to share the wonder of China's wildlife with the western world. She became the first explorer to do so, and set in motion a public fascination with these creatures that continues 80 years later. Part of "The Brain Scoop" series.
Snakes certainly make it look easy when they slither forward, leaving perfect S-curve tracks behind them, but scientists have long been puzzled by the mechanics of their locomotion. Now, after a series of experiments and some computer modeling, David Hu has cracked the case. With funding from the National Science Foundation, he’s using math to determine how snakes slither and it turns out they move in a much different way than scientists have long thought.
Provides an overview of all the stages to ensure a kitten grows up to become a happy, healthy, and much-loved addition to a family. Cats have an extra sense organ, and they can actually "taste" smell. In relation to their body size, cats have the largest eyes of any mammal. The cat's grace and beauty have inspired artists since ancient times. By Victorian times they became pampered pets. Cats are loving and affectionate but have an independent character that guarantees them a special place in the hearts of their caregivers. NOTE: Bonus material follows main feature.
This album of eight computer-animated video segments looks at the particle approach to studying light by exploring the antithesis of the wave model. Presents black-body radiation, Planck's constant, the photoelectric effect, and the work of James Clerk Maxwell as forerunners to Einstein's concept of photon frequency. Shows examples of a slope-intercept graph and a revised double-slit experiment using light-sensitive paper segue to an illustration of the Compton effect, establishing that light consists of a stream of particles. De Broglie's contributions introduce wave-particle duality, which some might consider an inadequate solution, although it represents the best that current science can do.
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 a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term screw. Part of the Science Video Vocab Series.
Professor Lawrence Gilbert and his team at the University of Texas at Austin have discovered a population of tropical butterflies that exemplify "evolution in action," and a rare research opportunity. Gilbert says they may be witnessing a species of butterfly splitting into two different species. The stars of this research are the Heliconius butterflies, found in Central and South America. Despite the genetic similarities between the two groups of the butterflies, one group is showing a color preference during mating. With support from the National Science Foundation, Gilbert and his team are working to gain insights about genetics, behavior, ecology, and evolution.
Hummingbirds live only in the Americas, and their diversity numbers 350 species. They are part-time carnivores that must catch animals that compromise ¼ of their diet. Demonstrates how they can hover, fly backward, and move their wings in figure eights at 200 wind-beats per second in slow and stop motion images. Also reveals that every night their bodies go in torpor (mini-hibernation) so they don't starve while they can't consume nectar. Also sees how they co-evolve with flowers through pollinating mutualisms, and acquired their aerial skills by evolving from ancestors of swifts, their nearest relatives.
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).
Biologist Ken Dial has documented in extraordinary detail how birds are put together and the mechanics of how they take to the air. With support from the National Science Foundation, Dial and his team at the University of Montana Flight Lab use x-rays and high speed video to better understand the mechanics of bird flight. Dial’s more than 2,000 flight hours as a pilot in a wide range of aircraft adds another dimension to his research. Perhaps, by mimicking what birds have learned over millions of years, aircraft wings could change shape to accommodate both slow and fast flight, or a helicopter propeller’s shape might be altered to be more efficient.
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.
At Virginia Polytechnic Institute and State University, Christopher Williams heads the effort to further advance 3-D printing with copper, a widely used conductor in electronics. Williams is using a process called binder jetting in which an inkjet printer selectively jets glue into a bed of copper powder, layer-by-layer. The printed copper product is then taken to a furnace to fuse the particles together. With support from the National Science Foundation, Williams is addressing a major challenge in the 3-D copper printing process, which is to eliminate the porosity that develops in the part during the process.

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, it is night time and Moko is watching the shooting stars from Totemie's village and is remembering how he once thought that a lady blew the stars in the sky from the embers of her bonfire. And suddenly, an immense star, a huge ball of fire, appears from the sky and falls to the depths of the forest. Totemie and Moko take off to see where the meteorite has landed and discover that a huge flaming rock has made a hole the size of a volcano's crater in the ground and is setting fire to the forest around it. Totemie is scared that the sky is angry and Moko, who remembers Mei Li begins to dance like she did while playing Alarick's flute. It begins to rain and slowly the flames die down. Moko thinks that the clouds must have seen him dance and heard his flute and come to save his new friend's land.
In this short animation film, a magnificent bird performs for the emperor inside a glittering palace. Its plumage is a blaze of color. A blackbird, watching enviously, tries to become the next bird to perform for the emperor. However, he soon learns that a golden cage can’t compete with the open skies.
