As shown on the History Channel. In the remote wastes of Siberia buried under snow are the remains of one of the greatest catastrophes that the Earth has endured. 250 million years ago, huge volumes of lava spewed out onto the surface--so much that it would have buried the whole of Texas under one mile of lava. At first the temperature dipped but then the greenhouse gases that escaped from the depressurized lava caused a massive global warming. It wreaked havoc, and 95% of the species on Earth became extinct. Yet life hung on and in time this disaster paved the way for the next phase of life on earth--the age of the dinosaurs.

Two MIT students discuss the relationship between photography and science. They use various methods and instruments to explain how long exposure photography can help measure the speed of an airplane, observe the rotation of the earth, or create light paintings.
This episode features stories on an innovative surf park in the North Wales countryside and an invention aimed at stopping police chases. Host Mo Rocca also highlights the history of flight starting with the Wright Brothers and finishing with the modern technologies of space. Part of "The Henry Ford Innovation Nation With Mo Rocca" series.
What does it take to get a sailboat moving in the water? With the help of some of the Bay Area’s top aerospace engineers, students learn that sailboats don’t simply rely on wind to push them forward but that there are other invisible forces that are fundamental to the process. In fact, the physical elements that make a sailboat sail are the same ones that make an airplane fly.
Travel to the Namib Desert and discover the key characters of some of the ingenious adaptations that allow animals to thrive in this harsh environment. The secret to life in this unique ecosystem lies in the distribution of airborne water and food sources. Part of the "Nature's Microworlds" series.
How does one become a jet engine mechanic? The researchers in the A to Z Career Lab investigate the roles and responsibilities of jet engine mechanics, and they report their findings to inquisitive students. Part of the "I Can Be Anything I Want to Be A to Z" series.
Second in the series of three productions designed to let students learn by doing, guiding them through the science and history behind the Wright Brothers' invention of powered flight. This second component contains segments that provide science background (Four Forces of Flight, Newton's Laws, and others) to help students understand aviation concepts. Additional segments show the teacher how to conduct activities (building models or demonstrations) and acquire materials to be used in these activities.
With support from the National Science Foundation, some Brown University scientists are doing extensive research on bats, studying everything from their agility in flight to the elasticity of their bodies. Researching a bat's evolution, its structure and biomechanics in flight will help scientists better understand evolution and could lead to the development of aerodynamic materials for more lightweight, agile aircraft.
Showcases innovative teaching techniques in higher education as performed by science and math professors at Hampshire College, the University of Massachusetts, and Springfield Technical Community College. Techniques include interactive learning, giving pyramid exams (a two-step exam that turns a test into an interactive learning experience), problem-based cooperative group work, using technology (as opposed to lecture), and more collaboration between colleagues.
Gravity is the most powerful and exacting force in the universe. It binds us together, its reach hangs stars in the sky and its grip crushes light. Without gravity, stars, comets, moons, nebulae, and even the Earth itself would not exist. Explore how science and humanity discovered, overcame, and utilized gravity. Learn what it takes to propel objects into the heavens, to ride a wave, or to ski down a slope. Take a front row seat as an astronaut subjects himself to the weightless wonders of the specially modified aircraft used to train astronauts known as the "Vomit Comet."
Join Dr. Knowledge as he takes young viewers on a fast-paced adventure to learn about energy and electricity. Shows what tools, appliances, factories, and everything from iPods to airplanes have in common. Each needs energy to do their jobs. But, where does that energy come from? We know we can get our power from a wall outlet, but that's only the beginning. Dr. K and the Inquisitive Minds team trace the electricity from the wall through the power grid to its source.
One might never know it, but the seemingly quiet Harvard Forest in Massachusetts is actually hard at work. Like other forests, it’s busy doing some serious global housekeeping, which is being monitored by scientists at Harvard University. With support from the National Science Foundation, researchers are studying forest ecology. That research includes determining how the forest responds to carbon dioxide in the atmosphere. Part of the National Science Foundation Series “Science Nation.”
Chemist Paul Edmiston’s search for a new way to detect explosives at airports led to the creation Osorb. A swellable, organically-modified silica, or glass, capable of absorbing oil and other contaminants from water. Osorb has become the principal product of a company called ABSMaterials, where Edmiston is now chief scientist. With support from the National Science Foundation, Edmiston and his colleagues at ABSMaterials are developing water remediation technologies for cities and industries. ABSMaterials is creating formulas to address various contaminants, including hydrocarbons, pharmaceuticals, pesticides, herbicides, chlorinated solvents, and endocrine disruptors. Part of the National Science Foundation Series “Science Nation.”
Third in the series of three productions designed to let students learn by doing, guiding them through the science and history behind the Wright Brothers' invention of powered flight. This third component contains the same "how to" segments from the second in the series (13692) and parts of the history and scientific concepts from the first in the series (13691). However, it also provides greater ease and flexibility in locating, reviewing, and pausing in and between segments than the other two productions in the series. Good for sharing with students to aid them as they build and experiment with kites, gliders, and rubber-band-powered planes.
Assembly line workers won’t be swapping stories with their robotic counterparts any time soon, but future robots will be more aware of the humans they’re working alongside. With support from the National Science Foundation, roboticist and aerospace engineer Julie Shah and her team at the Massachusetts Institute of Technology are developing next generation assembly line robots that are smarter and more adaptable than robots available on today’s assembly lines. Part of the National Science Foundation Series “Science Nation.”
As a boy growing up in Brazil 40 years ago, Marc Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now, with support from the National Science Foundation, the materials scientist and mechanical and aerospace engineer at UC San Diego, is conducting the first ever detailed engineering analysis of toucan beaks. He says makers of airplanes and automobiles may benefit from his findings. In fact, panels that mimic toucan beaks may offer better protection to motorists involved in crashes.
Matthew Schneps is a researcher at Harvard University with a doctorate in physics from the Massachusetts Institute of Technology (MIT). He also happens to have dyslexia, so reading has always been a challenge for him. That is, until he got a smartphone. Schneps soon found that for him, a smartphone was easier to read than a paper or a book. But, was it just him? Or, had he stumbled onto something that could help others with dyslexia? Part of the National Science Foundation Series “Science Nation.”
A quick glance at the marsh next to Saquatucket Harbor in Harwich Port, Massachusetts, reveals right away that some of the grass is missing. The cordgrass there, and all around Cape Cod, has been slowly disappearing for decades. Marine ecologist Mark Bertness of Brown University studies this critical ecosystem, which protects our coastal environment by nurturing a complex web of plants and animals, filtering nutrients, and serving as a critical storm barrier. Bertness says the marshes are being overrun by purple marsh crabs because their main predators, blue crab and finfish, are being overfished. So, the purple marsh crabs are free to gorge on healthy fields of cordgrass and once done feeding, they leave behind nothing but lumpy fields of mud.
