The Kichwa tribe in the Sarayaku region of the Amazon in Ecuador believe that humans, animals, and plants live in harmony. They are fighting oil companies who want to exploit their ancestral land. A delegation of indigenous people attended the 2015 United Nations Climate Change Conference in Paris, France to make sure their voices were heard.

Tells the story of a young Jane Goodall and her special childhood toy chimpanzee named Jubilee. As the young Jane observes the natural world around her with wonder, she dreams of being able to help animals, until one day she finds that her dream has come true. Dr. Jane Goodall becomes a renowned humanitarian, conservationist, animal activist, environmentalist, and United Nations Messenger of Peace. Based on the book by Patrick McDonnell.
According to some statistics, the economic damage from invading alien species might be costing the global economy more than any other form of environmental disruption: $1.4 trillion a year. Examines the price nations pay for failing to stop these invasions. Features a cast of leading villains: cane toads in Australia, zebra mussels and the Burmese python in the United States, and love grass in Brazil.
Humans construct boundaries around homes, neighborhoods, and nations to bring order to a chaotic world. However, they rarely consider how these boundaries affect the environment or others. Photographer Krista Schlyer and biologist Jon Beckman study how fabricated barriers influence the movement of wildlife. Schlyer and Beckmann have seen the damaging impacts resulting from the wall built along the Mexico-United States border. Humans probably will not stop constructing walls and fences any time soon, but planning the boundaries with wildlife in mind can help prevent these structures from causing environmental harm. Part of the "Think Like a Scientist" series.
Stacey Combes, a biomechanist at Harvard University, and her team are using high speed cameras to help them study how dragonflies pull off complicated aerial feats that include hunting and mating in mid-air. They can fly straight up, straight down, hover like helicopters and disappear in a blur. Combes is also exploring the use of dragonflies for mosquito control.
The world’s population is projected to increase by 2-3 billion over the next 40 years. Already, more than three quarters of a billion people lack access to clean drinking water and 85 percent live in the driest areas of the planet. Those statistics are inspiring chemist Ben Hsiao and his team at Stony Brook University. With support from the National Science Foundation (NSF), the team is hard at work designing nanometer-scale water filters that could soon make clean drinking water available and affordable for even the poorest of the poor. Part of the National Science Foundation Series “Science Nation.”
What helps seeds grow? Where do they come from? What is pollination? How does it happen? An elementary class experiments to find the answers. Time-lapse photography and illustrations reinforce the concepts.
Some things die and decay and others don't. A walk in the park teaches that leaves, logs, and animals are examples of things that decay or rot. An elementary class buries apple, potato, and banana skins, bread, a plastic tray, and an aluminum can. They learn what decays and what will not. Some things that don't decay can be recycled; those that do, enrich the earth.
An elementary class prepares for a visit from the Shadow Players, a group who use light, shadow, and color to tell a story. The class learns about sources of light, shadows, and silhouettes. They experiment with transparent, opaque, and translucent objects to see what lets light through. Using a prism, they discover the colors in light. Review at the end.
Where do baby animals come from? What do they look like? A family visits a farm in spring and learns the answers. Shows a duckling hatch and a lamb and calf being born. Viewers decide which creatures are born from eggs and which are born live. Later that spring, the family has a new baby.
A community of sea lions annually visits an island in the Gulf of California, where the babies are born and must be taught to swim. Compares seals and sea lions. Details physical characteristics, diet, behaviors, and enemies. The only enemy this "grizzly bear of the sea" cannot fight is fishing boats.
More than two and a half miles below the ocean's surface, the wreckage of the Titanic rests on the seafloor. The legend of the Titanic was larger than her size, and finding the wreck site opened a door to not only exploration and scientific study, but to salvage as well. The United States negotiated an international agreement with representatives of the United Kingdom, Canada, and France. This agreement recognizes the wreck site as a memorial to those who died and a wreck of great archaeological, historical, and cultural importance.
Space weather can have important consequences for everyday life, such as interference with radio communication, GPS systems, electric power grids, the operation and orientation of satellites, oil and gas drilling, and even air travel as high altitude pilots and astronauts can be subjected to enhanced levels of radiation. The United States Geological Survey (USGS) Geomagnetism Program monitors variations in the Earth's magnetic field through a network of 14 ground-based observatories around the United States and its territories, providing data in real-time to a variety of customers.
As shown on the History Channel. We are so familiar with the map of United States, but do we know why our states look the way they do? Every shape on the map tells a story about our past. Why is California bent? To cling on to gold. Why does Oklahoma have a panhandle? Because of shifting borders for slavery. Why does Missouri have a boot? Because of a massive earthquake. Examines how every state is a puzzle piece revealing the unique geography, political, and social history of America.
First in a three-part series exploring the history of race perceptions and behaviors towards races in the United States. Explores how recent scientific discoveries have toppled the concept of biological race. Follows a dozen high school students who sequence and compare their own mitochondrial DNA looking for a "race marker," with surprising results. Also looks at the history of racism in the United States, the advent of stereotypes based on physical attributes attributed to races, and somatotypes, with particular reference to African Americans.
Tornadoes claim hundreds of lives and cause billions of dollars in damages in the United States. With support from the National Science Foundation, computer scientist Amy McGovern at the University of Oklahoma is working to find answers to key questions about tornado formation. While video from storm chasers and data from Doppler radar can help meteorologists understand some aspects of tornadoes, McGovern uses supercomputers to find patterns in very large datasets. She also works with weather experts to help her sort out the information in the simulations. McGovern’s ultimate goal is to come up with reliable tornado forecasting system.
Throughout history, Soccer has united all the numerous countries and communities in a single festivity. While soccer has a long history and tradition, the sport also embraces technology to keep it at the forefront of the sporting world.
The United States Geological Survey (USGS) volcano seismologist, Seth Moran, describes how seismology and seismic networks are used to mitigate volcanic hazards.
Exotic wooly adelgids are defoliating hemlock trees in the eastern United States. Scientists from the U.S. Forest Service are enlisting the help of predator beetles to reduce the number of wooly adelgids.
United States Geological Survey geologist, Angie Diefenbach, describes how she uses GIS (Geographic Information Systems) software to study volcanic erupts and their impacts on society.
