The Biology and Chemistry of Soil Activity Kit
In this comprehensive kit, students use garden or schoolyard soil samples to conduct a thorough evaluation of soil. Simple, easy-to-follow techniques and staining procedures are introduced along with calculations of soil fertility, the role of soil microbes, pH and soil lime requirements. Students form conclusions from their data about the ability of different soils to support plant growth. These results can then be compared with data collected in the field. Materials for 50 students are included; a refill for consumable items is available (see Related Products, below). Recommended for grades 6 through 11.
