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.
Determining the hardness of a mineral is one of the most important tests used in mineral identification. Most rocks are aggregates of minerals. This rock, a granite pegmatite, is a mixture of mineral grains. It contains pink orthoclase, milky quartz, black hornblende and black biotite.ntacid tablets are made from the mineral calcite. It takes many minerals to make something as simple as a wooden pencil. The lead is made from graphite and clay minerals; the brass band is made of copper and zinc, and the paint that colors it contains pigments and fillers made from a variety of minerals.
