Geologist Classification Lab

This worksheet simulates a “Rock Sorting Lab” where students examine ten rock descriptions and classify each as igneous, sedimentary, or metamorphic. After identifying the correct category, learners write the number into the appropriate column on the chart. Each rock description highlights formation clues such as crystal size, layering, pressure, or volcanic origin. Students practice observational reasoning and scientific classification skills central to geology. The activity also improves comprehension by requiring students to analyze details and infer the correct rock type. This hands-on classification supports deeper understanding of Earth’s materials and their transformations.
