Description
Mr. Johnston and student teacher Mrs. Carter's 9th grade biology class did a soil experiment on Liberty Campus in Madison, AL by finding the texture, depth, color, structure, moisture and presence of rocks, roots and free carbonates. The class was characterizing the different horizons in the soil in a deep pit and by using the auger method (a shovel like tool that you force in the ground to retrieve dirt). Soil is very helpful to humans and animals. It contains water and inorganic nutrients, which is provided for the plants. The plants then are able to give off oxygen so plants and animals can breathe.
