AB1141 - $58.60
Soil is the bridge between the living and non-living world. Introduce students to how soil is formed. Students will perform a series of hands-on experiments to gain an understanding of the chemical, physical, and organic processes involved in rock...
AB1142 - $58.35
Our simple-to-use soil test kit measures concentration levels of nitrogen, phosphorus and potassium (15 tests each). A pH indicator and color chart are used to determine soil pH levels (30 tests for each). Step-by-step instructions allow your students...
FB1095 - $119.55
The soil under our feet is a wonderful place to explore the living world. Using ordinary soil samples and easy-to-follow techniques, students are able to conduct a thorough evaluation of the soil in your area. Students will identify the types of microorganisms...
FB0425 - $69.15
Americans generate over 210 million tons of trash every year! One of the biggest decisions voters will need to make in the coming years is “what are we going to do with all this trash?” In this activity, students will set up different types of simulated...
AB1143 - $456.95
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...
AP5313 - $77.50
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...
AP6165 - $25.70
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...
AP6434 - $72.70
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...
FB0646 - $257.45
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...
FB0426 - $17.50
This self-contained kit will enable you and your students to quickly assess soil pH and the relative amount of three key elements-nitrogen, phosphorus, and potassium (potash). Tests are as simple as dropping the contents of a capsule into the sample...
FB0592 - $84.40
The seven units of the Topsoil Tour enable students in grades 4 through 8 to examine, discover, and compare the physical and chemical properties of soil. Each student conducts tests for pH, nitrogen, phosphorus, potassium, and soil texture using safe,...
FB1923 - $20.75
Get the attention of this eco-minded generation as they discover that “healthy-looking” soil can contain traces of a toxic metal remaining decades after initial contamination. Students run an aqueous extraction on a dark, rich soil only to find that...
FB1924 - $40.50
“Toy X has been recalled due to lead” is a statement our students have unfortunately heard too much in the media lately. Use this guided-inquiry activity kit to challenge students to determine how lead can be removed from a sample of contaminated water....
FB1991 - $31.00
Hundreds of species of organisms are living right under your feet! According to the U.S. Department of Agriculture, a single spadefull of rich garden soil contains more species of organisms than can be found above ground in the entire Amazon rain forest....
