Elements make-up minerals and minerals are the building blocks of rocks. Minerals are found on Earth’s crust and are solid and inorganic (non-living). Third grade geologists matched and identified nine minerals.

Then, we used physical properties that scientists use to identify minerals. We applied the Mohs Hardness Scale, performed a streak test with pieces of porcelain, and identified luster and cleavage. Click here for more information about the property tests.
