Characteristics of Soil Activity

 

In this activity, students will observe a variety of soil types and describe the characteristics of these soils.  Soil is made up of air, water, recycling organisms, rock particles, and humus.  Different types of soils are defined by the different proportions of humus and rock particles they contain.  Humus is formed from the decomposition produced by recycling organisms.  The three types of rock particles are sand, silt, and clay.
