Soil, An Environmental Investigation.
National Wildlife Federation, Washington, DC.; Minnesota Environmental Sciences Foundation, Inc., Minneapolis.
This environmental unit is one of a series designed for integration within an existing curriculum. The unit is self-contained and requires minimal teacher preparation. The philosophy of the series is based on an experience-oriented process that encourages self-paced independent student work. This particular unit investigates soil in relation to acidity, moisture, minerals, and organisms. Students in grades 2-9 can discover how these factors are interrelated and what effects they have on the soil through the activities included in the unit. Techniques for determining soil pH with litmus paper and the presence of soil nitrates with test kits are included. Also, students make a sample of organisms in the soil with the help of a Berlese funnel. Each activity includes a list of the materials needed and where they can be found, background information, directions, and questions for discussion. (MA)
