Product Details

Do all types of soil hold the same amount of water? How much more water can one soil hold than another? Students perform three easy-to-follow lab activities to determine how pore size, soil texture, compaction and surface runoff affect the answers to these questions.

• Measure the drainage rate of dry versus wet soil.
• Determine the rate of water flow.
• Calculate permeability and porosity of different soil types.

Includes valuable Teacher Notes, detailed student background information, and reproducible data sheets. Complete for 30 students working in pairs.
