Why are trees and other plants green? Seems like a simple question, but the answer is full of surprises. Using a special camera that can pick up light just beyond the visible range, into the near-infrared, viewers get to see trees like never before. These otherworldly images can reveal not only why trees are green on Earth, but what color photosynthetic life on other planets might be. Part of the "It's Okay to Be Smart" series.
Join Jack as he meets up with six of the planet’s recently discovered animals. Some of the animals he visits with include the elusive okapi, adorable pygmy hippo, rare sun-tailed monkey, highly endangered mountain gorilla, and the see-through Fijian crested iguana. Part of the "Jack Hanna's Wild Countdown" series.
Actors portray prominent scientists and astronomers as they present the history of astronomy from Plato to Newton in its historical and cultural contexts. The Greeks reasoned that the universe was geocentric--the earth was at its center. Not until Copernicus did the theory of the sun as center take root. Each major astronomer declares his different theory until Newton's answers all questions about gravitational pull between planets.
The seemingly peaceful atmosphere in an organic garden on the University of Florida campus belies the battles happening among many of its tiniest inhabitants: the insects. For entomologist Christine Miller, there are endless opportunities here to study how insects compete and even fight for a mate. With support from the National Science Foundation, Miller and her team are researching mate selection and animal weapons as a key to better understanding animal behavior, diversity, and evolution. Understanding evolution is essential for figuring out solutions to modern problems such as antibiotic resistance, a major problem in medicine, and for understanding how life on the planet became so diverse and how it may change in the future.

How did the universe form? Where did it come from? Where does Earth fit into the equation? This segment focuses on Earth's place in the universe. Other topics covered include the solar system, gravity, planetary experience, and stars. Part of the "Earth Science" series.
Host award-winning geoscientist, Richard Alley provides an eye-opening look at some of the world's most important case studies in smart energy. Alley travels to Spain and Morocco where large-scale solar farms and individual photovoltaic panels atop tents in the Sahara are beginning to bring the vast potential of the sun down to Earth. In Brazil, abundant natural resources are transformed into efficient, sustainable biofuel, making Brazil the only nation whose cars could keep running if all gasoline were to vanish. In Denmark, and West Texas, citizens have taken sustainability into their own hands by becoming stakeholders in wind turbines. And in China, he explores multiple sustainable energy technologies, including exclusive footage from GreenGen, the world's most advanced low-carbon emissions power generation plant.

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. Phoebe is to participate in a slam-dunk during contest at half time of the big basketball game. The problem is Phoebe can't jump high enough. "If only gravity didn't pull on me." she moans. Never one to be tied down, Ms. Frizzle sends the class into space and turns the Bus into a planet — with adjustable gravity. The class finds basketball's a snap with low gravity and a riot with no gravity at all, but when there's way too much gravity, things get really heavy.
This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans. The Darién Gap is a remote tropical forest that has been home to indigenous people for thousands of years. As pressures from outside human development encroach on the forest, these communities are protecting their land using a cutting-edge tool: drones. Through a partnership with a nonprofit organization, the Rainforest Foundation, they map their community boundaries to secure land titles, create sustainable land-use plans, and monitor their forests against logging and ranching.
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."
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. From the spaceship, Leo sees some very strong rays coming from a sun. Afraid that something would explode, they consulted with Maqui. She tells them that the temperature outside is very dangerous. She also warns that a solar storm can start at any moment.

Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The kids and Maqui see a strange space object, it looks like a spaceship. Maqui studies it and discovers that it’s a space station. The space station was created for all kinds of scientific research: physics and biology investigations, astronomic monitoring and studies on human beings in space. The kids land in the station and meet its commander, a computer called Inteligentis.
In this episode, researchers reveal their findings of a cross-discipline analysis of ancient cemeteries. Their research sheds light on aspects of social organization and migration of 6th-century barbarians. Another segment discusses a new sensor based on an ancient African musical instrument that can detect adulterated and counterfeit medications.

Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The kids are surprised by a wicked alien named Kusini. He is an expert spaceship pilot and hopes to capture the fiends and lock them in a spatial zoo. They don’t know how to escape from him and his radars. Maqui explains to them ways to use gravity so they can increase their spaceship’s speed to outrun Kusini.
This University of Miami residence hall may look typical, but students in one of the apartments are participating in research involving one of the planet’s most precious commodities--water. With support from the National Science Foundation (NSF), environmental engineer James Englehardt and his team created a net zero water system, which serves most of the residents’ daily needs, including dish washing, showering and laundry. All of the water is treated just outside the building, and reused in a sustainable loop. Part of the National Science Foundation Series “Science Nation.”
To change a spacecraft's speed and direction, NASA engineers use a planet's or moon's gravity, a process called a "gravity assist." In this video, students design and build systems that use magnets to control the speed and direction of a rolling ball. As they build their systems, they use the engineering design process, apply a variety of science concepts, and learn how NASA spacecraft use gravity to help them explore the solar system. Part of the "Design Squad Nation" series.
The 1960s world population has nearly doubled and now tops 7 billion. Population growth, though little discussed, is putting an unprecedented burden on the planet's life systems. Brings to light the connection between overpopulation and our most pressing environmental and humanitarian problems, as well as the solutions. Also, follows Beth, an American mother and child rights advocate, who grew up in a large family of 12 as she travels to Africa to witness first-hand the impact of population growth in the developing world and its role in exacerbating poverty. While there, she meets a young Ethiopian woman, Zinet, who comes from a poor family of 12, but has found the courage to break free from long-held cultural barriers holding back women. Features a broader discussion of the solutions to overpopulation in both the developed and developing world.
