Description: "Using simple tests, students learn to identify sand, clay, and humus in soil. They also study how water affects different kinds of soi. Through long-term experiments, they explore how roots and plants grow in various soils and how, with the help of worms, old plants decompose and become part of soil. Then, applying what they have learned, they investigate their own local soil."--Page 3.
