Soil is not just dirt but an essential source of life and nutrients for many organisms, including humans. Soil provides a base for forests, fields, farms, and gardens and is necessary to many different kinds of animals and plants. Through investigations, students will learn that soils are composed of a variety of living and non-living things and earth materials; that there are different kinds of soil; and that the unique characteristics, composition, and condition of each soil type determine its capacity to sustain life.

I can use appropriate science and technology vocabulary, including clay, sand, loam, pebbles, humus, and soil, in oral and written communication
