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.
