Natural resources are created by Earth's processes and used as a source of energy for all life on Earth. While some are created over the course of millions of years, others are continually generated each and every day. In Natural Resources, students will examine both renewable and nonrenewable resources, touching on their sources and many uses. Discover the best methods of conserving nonrenewable resources, including how they are recycled and cleaned. A fun, hands-on investigation illustrates how students can observe the many different kinds of particles that can be found in the air, while a geothermal plant provides the setting for a look at how people can turn volcanic heat into electricity. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
