Live footage and colorful graphics teach students about regions and climates, and explain the impact environments and living organisms have on each other. A terrarium project demonstration shows students how they can make their own living ecosystems. Teacher's Guide available in disk and online: www.schoolvideos.com

Travel deep inside the Earth to discover how rocks and minerals are formed, to learn about the three types of rock, and to understand how rocks change over time through weathering and erosion. See the entire rock cycle and learn how geologists determine the properties of rocks. Learn about the structure and composition of minerals.

With the help of Luke Warm, a weatherman on the water channel, two young baseball players come to understand why the big game might be rained out as they are introduced to the key elements that make up and affect the water cycle.

Stunning NASA and live footage combine with state-of-the-art animation to give students a clear understanding of the physical features that shape our earth. Terms like escarpment, plateau, butte, outlier, and atoll are shown in their natural states with examples highlighted on an animated globe. Learn the names of these landforms and where they are found.

The surface of the land has undergone many changes over its history. Water, rain, snow, and wind they all continually shape and form the Earth. Take students on a journey to discover how physical weathering, chemical weathering, and erosion occur. Identify that the destructive forces of erosion and weathering are slow processes that change the surface of the earth.

Segment 1: Geologic Time (6 min.) Learn how absolute and relative times help scientists examine the Earth's age, as well as prehistoric life forms. Segment 2: Prehistoric Life (4 min.) Discover how fossils are formed and see the clues they give scientists to learn details about prehistoric life and the history of our planet.

Take a trip to a recycling center, a landfill, and a town dump to understand what happens to trash after it is thrown away. Focus on the environmental problems created by solid waste and discover ways to alleviate the problem. Learn that through daily conservation methods, people can control the amount of waste they produce.

Little on this earth can withstand the violent fury of an F5 tornado. A churning vortex with winds over 300 miles an hour, these tornadoes create immense swaths of death and destruction in a matter of seconds. But today, experts are exploring the supertwister's complex inner working in bold new ways in the hopes of one day being able to accurately predict the occurrences of tornadoes.

Our appetite for the earth's resources and consumer goods has led to increased levels of carbon dioxide entering our atmosphere, trapping more heat from the sun and leading to global warming of the atmosphere.

Getting outdoors is one of the great pleasures in life. But our expeditions into natural environments can also cause real horror stories to unfold. Discarded rubbish causes the waterways to become clogged, a campfire can leave a nasty visual scar that can last for years. How can we avoid causing these problems? This program examines ways to minimise our impact when enjoying the outdoors.

What exactly are greenhouse gases? Are they really causing climate change? Global warming has suddenly become the hottest environmental issue, and this program clearly explains the science of the greenhouse effect and the evidence that we are causing climate change.
