Soil Particle Density
Students will measure the volume of a known mass of dry soil particles and calculate the density of the particle portion only of a soil sample.
Protocols to help in completion of the main protocol
Students will measure the mass of a dry soil sample of known total volume including pore space to determine the density of the whole sample.
Students will use a technique chosen by their teacher 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.
