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.

We are learning about Soils in the environment.
I can explain why soil is an important resource
I can explain the impact humans have on our soil environment (positive / negative)
I can identify and describe the different types of soils
I can investigate the components of soil (e.g., nonliving things such as pebbles and decaying matter; living things such as organic matter, bacteria, earthworms, and insects), the condition of soil (e.g., wet, dry), and additives found in soil (e.g., pesticides, fertilizers, salt)
I can use appropriate science and technology vocabulary, including clay, sand, loam, pebbles, humus, and soil, in oral and written communication
