Metamorphic rocks form through heat and pressure deep within the Earth's crust. This 12-piece Metamorphic Rock Kit provides students with hands-on learning about rock transformation processes, showcasing different textures and mineral compositions.Educational Benefits: Demonstrates how heat and pressure cause rock metamorphism. Helps students identify foliated vs. non-foliated rocks. Encourages analysis of mineral composition and texture changes. Classroom Integration Ideas: Create a before-and-after comparison of sedimentary rocks vs. metamorphic versions. Use magnifying glasses to observe crystal growth and layering. Discuss how metamorphic rocks form in mountain-building processes. Features: Includes 12 metamorphic rock samples, each approximately 3cm:: Anthracite Coal Banded Gneiss Coarse Marble Fine Marble Garnet Schist Mica Schist Phyllite Pink Quartzite White Quartzite Red Slate Green Slate Slate High-quality samples, professionally curated for detailed study.
