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.
