Protocol
Use this protocol and a GLOBE Soil Fertility Kit to prepare samples and determine whether nitrate, phosphate, and potassium are absent from a soil sample or present in low, medium, or high concentrations.
Protocols to help in completion of the main protocol.
This protocol guides you in using a technique to expose a soil profile for characterization.
Step-by-step instructions for collection data according to the protocols.
Sheets to be filled out during data collection.
Activities to help students learn more about the instruments and protocols.
Students will understand the geologic phenomena of weathering and erosion. These processes, along with deposition, shape our landforms and contribute to the development of parent material in the soil formation process.
An activity which highlights the importance of learning about the soils on Earth. In this activity students explore some of the many uses of soils, learn the five soil-forming factors, and gain a better understanding of how little of Earth's surface is covered in soil.
