STC Program: Soils Unit Kit, 3rd Edition

In Soils, students investigate the chief components of soil (sand, clay, and humus) and the relationship between soil and plant growth. They create their own compost bags to observe decomposition of organic materials over time. Students observe and read about earthworms to learn about their connection to plant roots and soil. They also conduct tests to observe and compare such properties of soil as odor, appearance, and texture. Settling, water content, and soil consistency are explored.
