Drag each label to the correct location. Geologists study a variety of other characteristics to identify minerals, such as texture, magnetism, streak plate markings, density, and specific gravity. Use the information you have already gathered, in addition to a few other properties of minerals, to identify the seven minerals in the chart below. If you need help using the graduated cylinder or scale, consult the lab instruments and measurements guide. If you do not have access to the seven minerals given, use this resource to complete the chart.
