=Rocks and Their Properties=
 * 1) Give a simple explanation of what a mineral is and some examples, e.g., quartz, mica. //Observe and describe the characteristics of ore minerals such as magnetite and hematite (two sources of iron).//
 * 2) Identify the physical properties of minerals (hardness, color, luster, cleavage, and streak), and explain how minerals can be tested for these different physical properties. //Acquire a collection of minerals that includes (a) duplicates of the same mineral, somewhat different in appearance (size, shape, exact color) and (b) samples of minerals that look similar but are actually different. Examine minerals using a hand lens. Look for and record similarities and differences such as heaviness, color, texture, crystal shapes, luster, surface patterns, etc. Sort as accurately as possible. Report total number of different minerals present, and how many duplicates, if any, of each type. Use simple tools to test for hardness, e.g. Moh's Scale of Hardness.//
 * 3) Identify the three categories of rocks (metamorphic, igneous, and sedimentary) based on how they are formed, and explain the natural and physical processes that create these rocks.
