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.
Color is important in mineral identification, but it can be a complicated subject. Experts use color all the time because they have learned the usual colors and the usual exceptions for common minerals. If you're a beginner, pay close attention to color but do not rely on it.
How would you try to identify your mineral? If you were a mineralogist, you would use certain properties to identify the mineral. You can observe some properties by looking at the mineral. For example, you can see that the mineral in Figure 3.12 is the color of gold and is shiny. But, you cannot see all mineral properties. You need to do simple tests to determine some properties, such as how hard the mineral is. You can use a mineral's properties to determine its identity because the properties are determined by the chemical composition and crystal structure, or the way that the atoms are arranged. Figure 3.12: You can use the properties of a mineral to identify it.
