Product Details

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!
