A sensational collection that reveals the varied geological specimens found in the United States. Collection includes specimens from each of the 50 States. The rock, mineral or fossil selected to represent that state is individually "keyed" for identification. The key also includes a useful fact and a geologic feature for each individual state. Specimen size 1" x 1" x 1". Grades 3-12. Ages 8-18.

The study of rocks is an essential part of studying the age and evolution of Earth. In Rocks, students will examine the characteristics of each of the major types of rocks: igneous, sedimentary and metamorphic. From stalactites and stalagmites to intrusive and extrusive rocks, students will examine how rocks are formed in this exciting program. A visit to Mammoth Mountain in California showcases the interesting rock formation known as the Obsidian Dome, while a fun, hands-on demonstration illustrates how different sized-particles of sediment settle out of water at different rates. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Fossils are historic blueprints -- remnants of plant and animal life that preceded us. In Fossils, students will examine molds, casts and imprints of various living things, and discover how scientists place the age of these ancient remains and the methods they use to preserve them for future generations. Find out how paleontologists discover fossils and what these discoveries tell us about the past. Take a trip to the Petrified Forest, and examine tree trunks that were turned to stone millions of years ago. A fun, hands-on investigation demonstrates for students how they can create four different simulated environments in order to test each for its ability to preserve remains. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Fossil fuels were formed millions of years ago as part of a natural process in which the remains of dead plants and animals were buried and placed under extreme pressure and heat. Coal, oil and natural gas are the most important fossil fuels. But what are they used for, how do we find them and what can we do to preserve our limited supplies? Students will find the answers to these questions and more in Fossil Fuels as they explore these nonrenewable resources of Earth. A fun, hands-on investigation demonstrates a creative alternative to using fossil fuels in the creation of plastic and a visit to an oil platform showcases how this valuable fossil fuel is pumped up from the bottom of the ocean. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Minerals are an important part of everything around us -- from the pencils we write with to the airplanes in the sky. Even the earth beneath our feet is packed solid with these essential building blocks. In All About Rocks and Minerals, children will discover the characteristics of minerals and see how different minerals make up different kinds of rocks: igneous, sedimentary and metamorphic. A visit to a lapidary shop examines some beautiful gemstones, while a fun, hands-on investigation demonstrates how solid crystals can be made from a liquid. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.
