Disney Educational - Bill Nye The Science Guy - Earth's Crust
Bill Nye deals with the crust of the Earth in this episode of his award winning series. While he uses many devices to connect with kids, including humor and general silliness, he never condescends. In Bill Nye the Science Guy: Earth's Crust, the Science Guy takes a tour into the layers of the Earth, all the way to the "gooey center." A hint of the core's heat comes when volcanoes erupt and hot lava flows.
Over the course of its 4.5 billion-year history, Earth has undergone a great number of changes -- from a red-hot ball of molten lava to a planet with an environment capable of sustaining life. In All About Earth's History, children will trace the evolution of Earth and the organisms that populate it. Young viewers will take a peek deep inside the Earth, examining its varied layers while discussing how scientists use fossils to help map out the complex time line of events that has changed Earth over millions of years.

"Radioactivity is like a clock that never needs adjusting," writes Doug Macdougall. "It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating--the best known of these methods--and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves--James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson--Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.
Earth's Children is a series of historical fiction novels set in upper paleolithic times, based in many locations across Europe, south of the great sheets of ice that covered the world at that time. It mainly covers the experiences of the protagonist Ayla with various cultural groups of Cro-Magnon humans as well as with the genetically and culturally distinct Neanderthals.
The series is based largely on archaeology and anthropology, with healthy doses of romance and poetic license.
