Introduces water and its properties and uses. Shows water's three forms: liquid, gas, and solid and how it changes form through evaporation, condensation, and freezing. Emphasizes that all living things need water to survive. Demonstrates the water cycle and discusses ways people use this essential liquid.
Steppes, pampas, savannahs, prairies--all are names for the grasslands that are found on most continents. Uses the American prairie to highlight characteristics of grasslands, different kinds of grasses, and examples of plant and animal life. Notes humans' impact on this biome.
Describes the characteristics of river biomes and their diverse plant and animal life. Notes effects of their passage through varied geography and climates. Human impact on rivers remains both beneficial and harmful.
Salt marshes, bogs, swamps, and freshwater marshes are examples of wetlands, each one home to wide varieties of plant and animal life. This type of biome is a complex ecosystem that benefits people and upon which humans have had destructive impact.
Superhero Bruce Rain must stop a tornado, a blizzard, and a hurricane. As he races to stop the storms, Dr. Mother Nature explains the relationship between wind and severe weather. Part of "The Science of Climate" series.
Host Emily Graslie travels to an unstudied rain forest. While there, she helps a team of scientists document the reptiles and amphibians they find during night excursions. Part of "The Brain Scoop" series.
Provides an overview of magnifiers and microscopes. Identifies a microscope's parts, use and care, and shows how to handle slides. Covers the development and changes of the microscope and its contribution to scientific discovery. Compares the standard light and the electron microscopes. Uses multiple examples of magnification to show why this tool is important to research.
Part of the animated "Johan, the Young Scientist" series. Housebound during a rainy day, Johan goes to ScienScape where it also rains. Johan, Ani, and Moki set out to find where the rainwater ends up. This leads them from gutters to drains to rivers. They soon learn that all living beings need water to survive.
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 different types of precipitation including snow, rain, sleet, hail, and freezing rain. Also discussed is the water cycle's role in dispersing precipitation throughout the world. Part of the Science Video Vocab series.
Rendered in woodcut-inspired 2-D, this short animation serves as a comic warning about the devastating effects of clear-cutting rain forests. The story unfolds in a lush jungle inhabited with exotic creatures. Suddenly, a chain saw can be heard in the distance, followed by the sound of trees crashing to the ground.

The endocrine system maintains the body's delicate chemical balance. Describes the location, function, and effects of the major endocrine glands, and notes their close relationship to the nervous system. Some discussion of diabetes and hormonal imbalances.
Everyday, real-life examples demonstrate the processes of weathering and erosion. Easy-to-understand examples of weathering help students differentiate between the processes of mechanical and chemical weathering. Footage of weathering and erosion processes help students grasp how each process alters the environment. Important terminology includes: mechanical weathering, landslides, abrasion, freezing, thawing, chemical weathering, oxidation, acid rain, moving water, wind, and glaciers.
Host Lisa Van Pay visits the scientists and engineers working to make the electric car of the future a reality today. One of the toughest parts is storing enough potential energy in the battery. Graduate student Katharine Stroukoff from the University of Texas-Austin explains how her research may help build a better battery, while Mike Nawrot and Dan Lauber, members of the MIT electric vehicle team, describe the advantages of their fully electric Porsche 914.
In this episode, host Steve Backshall lifts the lid on an incredible world of intricate relationships and unexpected hardships in the Amazon rain forest. He explores the way that the jungle's inhabitants interact and reveals a hidden secret that might just be what keeps the whole place alive. Part of the "Nature's Microworlds" series.
If the sun instantly switched off like a light bulb, it would take almost 8 and a half minutes before humans on Earth realized what happened. Light travels at the fastest speed there is, but it still takes almost 500 seconds to get to Earth. This means the sunlight that reaches Earth is old. How is that possible? It is due to the concept of random walks. Part of the “It’s Okay to Be Smart” series.
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 learns about water tables and how streams develop. During the dry season, the river level drops and the remaining water turns to mud. He can't swim or drink the water. A man with a strange stick points the stick to the ground, and when Moko digs down there, water gushes out! Moko learns that even if no rain falls, Mother Earth could still be generous if you know the right way to ask her.
Marine debris comes from many different sources and enters the ocean in many ways. Intentional littering and dumping are big causes. Sometimes the trash goes directly into the ocean, and sometimes marine debris is indirectly generated in a city hundreds of miles from the ocean. When someone litters on the street or parking lot, rainwater can move the trash into storm drains that empty into streams, rivers, and other bodies of water. Improper or careless waste disposal also contributes to this environmental concern. Part of the "Trash Talk" series.
Canada's coastal forest is part of an ancient forest system of redwood, spruce, and cedar trees. It is also home to some of the largest aggregations of top predators in North America. The trees of this forest are huge, and forest productivity here rivals even some of the world's biggest tropical rain forests. Part of the "Nature's Microworlds" series.
