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.
There are four criteria that must be met in order for something to be called a mineral: 1  Not formed from the remains of plants or animals; that is, inorganic. 2  Naturally occurring, not man-made. 3  Has the same chemical makeup wherever it is found (Ex: Quartz is always SiO2)
