To help eighth-grade students experience the excitement of Earth science research, the authors developed an inquiry-based project in which students evaluated and cataloged their campus geology and soils. Following class discussions of rock-weathering and soil-forming processes, students worked in groups to excavate multiple soil pits in the school yard. They collected soil samples to study the characterization of soil morphology and to conduct petrographic (i.e., thin-section) and scanning electron microscope (SEM) analyses. Students gained hands-on geospatial and mathematic skills from recording compass, distance, and orientation measurements while establishing a base map for their campus research site.
