Professor Trujillo demonstrates the property of Heat Capacity and the different abilities of water and air to absorb heat.

Earth has got swirl. The air in the atmosphere swirls. The water in the ocean swirls. But what does it all have to do with weather and climate? To answer this, we’ll have to get a close-up on all that swirl. Don’t worry, being dizzy is fun! Topics include: Earth's Place in the Universe; Investigating Earth's Past; Restless Earth; Mountains, Volcanoes, and Earthquakes; Energetic Earth; Atmosphere and Oceans; and Earth Systems.

A volcano is going off in Iceland, and Doug gets there fast. The volcano's lava contains rare material from the beginning of Earth's 4.5-billion-year history. Iceland is defined by its geology, and Doug relishes giant waterfalls roaring over ancient lava flows; ice caps, icebergs, glaciers, and geysers; and how the island is split down the middle by the parting of two massive tectonic plates.

This live-action video program is about the pseudo-ruminant digestive system. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated graphics and labels. Viewers will see and hear the word used in a variety of contexts providing students with a model for how to appropriately use the word. Related words are also used and reinforced...

The fascinating geologic processes of mountain building, seafloor spreading and volcanoes are a few examples of the power of plate tectonics. Footage filmed on-location in Iceland, the Canadian Rockies, and Crater Lake help viewers understand the theory of plate tectonics. Colorful animations illustrate the movement of tectonic plates and the role this plays in the development of geologic features. Other terminology includes: theory of continental...

In January 1700, a massive subduction earthquake devastated a portion of the Oregon-Washington-British Columbia coast. Ten years of research and increased seismic activity have led scientists to believe that another is likely to occur in the same vicinity. This program explores the evidence that remains from that 17th-century quake, including ghost forests, debris from tidal waves, and historic references including Native American legends and the...

Drill down to discover the treasures beneath our feet that power our world. Fossil fuels–coal, oil, and natural gas–powered the industrial revolution and allowed us to build a way of life that many cherish today. Personal cars, planes, lights, hot showers–all of these are gifts from our fossil fuels… but they have a dirty dark side in that they are polluting the planet. What is it about these natural resources that has allowed them to fuel...

This live-action program teaches students that, for food to be of use to our body's cells, it needs to be broken down and absorbed into the blood stream. This is the job of the digestive system, a complex series of tools that includes teeth, saliva, bile, acids and enzymes designed to reduce nutrients to a form that can be delivered to cells. Students will come to understand that waste products and indigestible materials must be removed from the body....

The orbiting satellites are giving scientists insight into deep water supplies on Earth.
