Follow-up Teaching Notes: • Provide background on the three basic rock types: igneous, sedimentary, and metamorphic. • Have resource books available at each station in case students need help with identification. • Have students record their findings in their notebooks. Expansion: – Measure mass and density with an electronic scale, graduated cylinder, displacement can, and calculator. – What are cleavage and fracture, and how do different minerals types demonstrate it? – Explore how weathering and erosion impact rocks and sediments. – Explore the ways minerals are formed and how that impacts the physical properties students observe. – What types of rocks would we expect to find at different layers of the earth or regions around the world? Disposal/Clean-up: • Put the minerals can and test equipment back into their containers. Any spilled HCl should be wiped up with a paper towel and disposed of properly.
