pH of Soil—Super Value Laboratory Kit
By: The Flinn Staff
What are the pH values of the soil in your area? What
could cause soil to have a low or high pH level? Students will find answers to these questions and more as they perform this easy-to-follow procedure to find soil pH values! Students use a pH indicator solution, collected soil samples and sampling cups to accurately measure the pH of their local soil samples. Soil pH values between 4 and 10 can be precisely determined. Kit includes detailed instructions and background sections.
Super Value Kit is complete for 5 classes of 30 students working in pairs with enough indicator solution for over 500 tests!
Porosity and Permeability—
Column Kit with Beads
How does porosity and permeability affect groundwater aquifers? Students, through experimentation, will learn about pore size, permeability and particle size. Help students learn these important concepts and integrate math, measurement and percentage skills. Kit includes all materials for one complete demonstration setup and detailed instructor’s guide.
Porosity and Drainage Rate of Soil—
Student Laboratory Kit
By: The Flinn Staff
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 Instructor’s Notes, detailed student background information, and reproducible data sheets.
Complete for 30 students working in pairs.
Soil Analysis Kit
Students experiment with easy-to-use soil test procedures to determine soil pH, nitrogen, phosphorus and potassium concentrations. Chemicals and materials are provided so each test can be performed 50 times. Each test is separately packaged so several teams of students can work simultaneously. Each kit contains materials and instructions to conduct the four tests mentioned above, a soil texture and classification unit, soil sampling tube, soil sample bags, and the book A Study of Soil Science. Materials are conveniently packaged in a polypropylene case.
