13528	All About Soil	23 min.	2000	K P I
Soil is the loose top layer of the Earth's surface, but what is it made of? How does it form? And why is it so important? In this video, children will learn what components are needed to make the best soils for growing plants while discovering the important role that the forces of erosion play in the creation of this valuable resource. A visit to a grade school showcases a unique program that uses lunch leftovers and hungry earthworms to improve the soil in the school's garden, while an informative demonstration illustrates how sand is created from the continual erosion of rocks. Includes a teacher's guide.
12836	Dirt:Nature's Sandbox	10 min.	2000	K P
Most children love dirt! They love to dig in it, build in it, explore in it and just plain get dirty in it. And while they play, kids notice that there is life in the dirt, that water and dirt mix to make mud, and that roots from plants and trees can be found burrowed under the soil. This imaginative video helps youngsters understand the real importance of dirt and begins a basic introduction to the natural nature of earth and the study of science. Introducing concepts of: soil, roots, humus, minerals, plants, water, mud, insects, erosion, environment, nutrients, pollution, bacteria, clay, silt, and sand.
10345	Exploring Geology	10 min.	1990	K P
Introduces the key learning concepts of geology. A series of experiments identifies three different types of soil and rocks, and shows how rocks erode or break down into soil through the effects of wind, water, friction, and pressure. Viewers gain a better understanding of the great variety of surfaces on the earth, the important resources they provide, and the need to take care of the earth.
10175	Soil: An Introduction (2nd Ed)	12 min.	1991	P I
Investigates soil and its vital role in maintaining life on earth. Most of the earth's food comes from soil and so without it, life on earth would not be possible. Looks at the time it takes for soil to be rich enough to grow things and the many factors which must occur to enable this layer of Earth to be developed and retained. A Norman Bean Film.
