Minerals: Identifying Minerals

Upon viewing the Minerals video series, students will be able to do the following: Define minerals as naturally occurring solids that have a definite chemical makeup and crystal shape. Explain that a crystal is made of particles that form a repeating pattern. Understand that most minerals are comprised of two or more elements, which are chemically pure substances. Differentiate between silicate and nonsilicate minerals and give examples of both. List and define different mineral properties, such as color, hardness, streak, and luster. Identify common problems associated with classifying or identifying minerals based on their color. Explain how Mohs hardness scale can help determine the hardness of minerals. Differentiate between cleavage and fracture. Explain how minerals are formed from molten rock on or beneath Earth's surface. Understand how changes in temperature or pressure can alter rocks to form different minerals. Know that some minerals form when mineral-rich water evaporates.
