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 to extrusive rocks, students will examine how rocks are formed. A visit to Mammoth Mountain in California showcases the interesting rock formation known as the Obsidian Dome, while a demonstration illustrates how different-sized particles of sediment settle out of water at different rates.
