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.
