Here are some ideas: 1  Serve baked potatoes with salsa or broccoli and sprinkle about one ounce of shredded cheese on top. 2  Make oven-baked 'fries' that are low in fat and calories. 3  Make mashed potatoes with low-fat sour cream, nonfat milk and chives.  Potatoes cooked in the microwave do not contain acrylamides.
This module, the second in a series on minerals, describes the physical properties that are commonly used to identify minerals. These include color, crystal form, hardness, density, luster, and cleavage.
Since varied temperature and pressures will produce different minerals, the exact type of metamorphic rock produced depends on the grade (intensity) of metamorphism. The grade of metamorphism can most often be determined by the minerals present within the metamorphic rock and the type of rock formed. Some of the more common metamorphic minerals include quartz, feldspar, biotite, muscovite, chlorite, garnet, tourmaline, calcite, and amphibole.
