All About Weathering & Erosion (DVD)
All About Weathering & Erosion (DVD)
D029

The surface of the Earth has undergone many changes over its history. Natural forces such as wind, rain, temperature and the activity of living things continually shape the visible landscape. In All About Weathering and Erosion, children will discover how these forces combine to form Earth's features. Examine the different forms of physical and chemical weathering that affect the Earth, while touching on both the problems and benefits that erosion has on the people who inhabit the land. An informative, hands-on demonstration shows how to construct a model glacier in order to see the effects glaciers have on the Earth, while a visit to Mt. Rushmore examines the effects of weathering on the world's largest sculpture. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.

All About Natural Resources (DVD)
D024

Natural resources include sunshine, fresh air, plants, animals, minerals and fossil fuels like coal, oil and natural gas. These things are resources because they are needed by living things. They are "natural" resources because they are all products of nature. In All About Natural Resources, children will learn about these resources and more, discovering along the way what makes some natural resources renewable and others nonrenewable. See how wind turbines provide an alternative to fossil fuels as a means of providing energy, while a fun, hands-on demonstration shows children how they can build their own simple water treatment system.
