Many properties are used to identify rocks and minerals. Choose a mineral, igneous rock, or metamorphic rock and describe how it exhibits one of those properties. Include additional information about your mineral or rock, such as its other physical characteristics, its uses, where it is found, how it forms, and/or other fascinating facts about it. If possible, include a sample photo of your mineral or rock. You can choose a property that has already been discussed for a different mineral or rock.
