Soils

Bar Code: 1204, 2276





Descprition: In Soils, students investigate the chief components of soil--sand, clay, and humus--and explore the relationship between soil and plant growth. Early in the unit, they create their own compost bags.This activity enables them to observe the decomposition of different kindsof organic materials over time. Students observe and read about earthwormsto learn about their connection to plant roots and soils. The studentsalso conduct tests that enable them to observe and compare such propertiesof soil as odor, appearance, and texture. Phenomena such as settling, watercontent, and soil consistency are also explored. These are then relatedto plant growth, as students plant cucumber seeds in a clear plastic tube.By observing root growth, students learn about the role of roots in keepingthe plant anchored and upright. In a final activity, students apply whatthey have learned to investigate a sample of local garden soil.
