A total eclipse of the sun is the greatest spectacle in our solar system. Gives an in-depth explanation as time-lapse images capture the full impact of this event. Begins with a discussion of lunar eclipses before moving on to examine auroras. Explores the causes of auroras, and gives examples of two: the Aurora Borealis and the Aurora Australis.

Tracy Drain is a flight systems engineer at NASA's Jet Propulsion Laboratory in Pasadena, California. As a child she became interested in space, and now she makes sure all the parts and systems in a spacecraft work as expected. She enjoys solving new, complicated problems. Part of the "Design Squad Nation" series.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will focus on the functions of the human skeletal system. Part of the Science Video Vocab Series.
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 solar system. Part of the Science Video Vocab Series.
Astronomers are beginning to locate thousands of planets that exist outside of the solar system. Scientists provide a behind-the-scenes look at the simple technique that astronomers are using to discover these curious new planets. Part of the "Science Out Loud" series.
Our Sun is a nuclear reactor converting hydrogen to helium continuously. X-ray and telescopic images reveal the Sun's photosphere and chromosphere, sun spots, solar flares and winds, and prominences. Describes each and its impact on Earth. Covers some of the Sun's mysteries, and projects what will eventually happen to our closest star.
What happens in your brain when you get lost or forget something? Johns Hopkins University Neuroscientist Amy Shelton believes she can find the answer. With funding from the National Science Foundation, she’s testing human spatial recognition. Study subjects learn and recall their way around a virtual maze while an MRI scans their brains. By analyzing MRI images of blood flow in the human, Shelton can get a picture of how the brain learns and recalls the spatial world outside the body. By understanding those processes, she believes she can develop techniques that will help improve human memory.
The city of Ann Arbor, Michigan has turned to engineering research to tackle an issue facing many cities: aging stormwater infrastructure during a time of tight budgets, growing populations, and more extreme weather. With support from the National Science Foundation, civil and environmental engineer Branko Kerkez and a team at the University of Michigan are building a new generation of smart and connected stormwater systems. Part of the "Science Nation" series.
In 1977, Voyagers I and II left Earth for deep space exploration and a close-up view of the edges of our solar system. Reveals how the space shuttles used the gravitational fields from surrounding planets to slingshot themselves through the outer planets. Voyager II's graphics and real pictures of Neptune and Uranus help explain their features, axis, rings and moons, and magnetic fields. Also notes some peculiar facts about each.
Scientists believe that Saturn, the second largest planet, would float in water if a glass were big enough. Uses computer graphics to note its features and those of its seven rings. Discusses Titan, its largest moon, and the Cassini probe, which examines it. Notes Saturn is a gas giant, has a 30-year orbit, and that astronomers create theories about this planet based on limited facts.
Firefighters risk their lives every time they run into a burning building. But, new technology may soon be watching their backs, no matter how far they venture into the flames and smoke. With support from the National Science Foundation, TRX systems is developing a new sensor system that can track firefighters where GPS units often fail.
The sun's powerful, warm rays light up the sky with brilliant color and heat. The changing cycles of the sun can affect the earth and its living organisms. The sun is similar to a living organism-just as humans are born, grow older, and die, so too will the sun. When this happens, the rest of the solar system will have no future.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the measurements of the International System of Units (SI). Part of the Science Video Vocab series.
The human body needs to take in food and water found in the environment, and through a sequence of mechanical and chemical processes, it converts that food into nutrients that sustain all the body's activities. The digestive tract alone has nine major organs devoted to this process, and the renal tract has three. Join Dr. Mark Reisman as he provides you with a look at the anatomy and physiology of the many organs and structures of digestion. Lastly, explores the properties of metabolism and nutrition.
Sirens are a small part of the sophisticated warning system used for tsunami alerts. Meteorological agencies issue warnings and send alerts to television and radio channels, the Internet, and mobile phone networks. These systems are found throughout the world and are vital for tsunami prone areas like Japan. Part of the "Danger Zone" series.
With support from the National Science Foundation, astronomers Marc Buie and John Keller are involving citizen scientists from throughout the western United States to participate in the Research and Education Cooperative Occultation Network (RECON). The project has provided telescope equipment and training to 14 small western U.S. communities north and south of Reno, Nevada, where night skies are clear and dark. When RECON students look out at the night sky, they look way out to the Kuiper Belt, a ring of icy debris that litters the Solar System out beyond Neptune. The network is looking to determine the sizes of Kuiper Belt objects as they pass in front of distant stars. Part of the National Science Foundation Series “Science Nation.”
Locked-in syndrome is a condition in which people with normal cognitive brain activity suffer severe paralysis, often from injuries or an illness such as Lou Gehrig’s disease. Boston University neuroscientist Frank Guenther conducts research on how brain regions interact, with the hope of melding mind and machine, and ultimately making life much better for people with locked-in syndrome.
The goal of this research is to determine the mechanisms underlying predatory and defensive behavior guided by an extraordinarily novel sensor in snakes. Pit vipers, pythons and boas possess special organs that form images in the brain of the thermal environment, much like vision occurs in the human brain. Thus, these snakes see heat, and this amazing system is the most sensitive infrared detector on Earth, natural or artificial. A better understanding of infrared-based thermal imaging in snakes is important not only for understanding complex behavior in these highly efficient predators, but also for understanding the evolution of imaging sensors and the behaviors they support in other animals including people. Part of the National Science Foundation Series “Science Nation.”
Students learn the process of weighing common objects. Concepts and terminology include matter, mass, weight, scale, and metric system.
Human beings, like every living organism, are driven by two inherent needs: to survive, and ultimately, to reproduce. To accomplish the goals of survival and reproduction, we have inherited bodies crafted by evolution so that every individual human organism is an organic super factory, a living machine made up of systems that process fuel, build products, repair damage, expel waste, and defend against invaders. Introduces the complex physiological systems of the human body: muscular movement, digestion, circulation, respiration, nerves, glands, immunity, and reproduction. Also, illustrates and explains the cellular basis of life and the importance of carbon in organic chemistry.
