Soil Particle Size Distribution
Soil Particle Size Distribution
Protocol
Students will suspend a known mass of dry soil in water and measure the specific gravity of the suspension after sand and then silt has settled out of the suspension to determine the amount of each soil particle size group in the sample
Supporting Protocols
Protocols to help in completion of the main protocol
Students will use a technique chosen by their teacher to expose a soil profile for characterization.
Field Guides
Step-by-step instructions for collection data according to the protocols.
Data Sheets
Sheets to be filled out during data collection
Learning Activities
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.
