2.03 discuss the different kinds of soil. Display piles of three different types of soil- sand, clay, loam. Ask students if all three piles are soil. Soil is a very important natural resource. Soil is made of many different kinds of matter.
Most soil is made of weathered rocks.
Soil also contains matter that was once living. The remains of dead plants and animals have become part of the soil. The easiest way to get a soil profile is to use a shovel to cut out a square on the side of a road. Lay the profile on its side in a box. If a profile cannot be obtained, use a picture of a profile.
