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.
Olivine always has silicon and oxygen as well as iron or magnesium or both, (Mg, Fe)2SiO4. The physical properties of minerals include: How physical properties are used to identify minerals is described in the lesson on Mineral Formation. Mineralogists divide minerals into groups based on chemical composition. mineral is formed through natural processes and has a definite chemical composition. Minerals can be identified by their characteristic physical properties such as crystalline structure, hardness, density, flammability, and color. Minerals are crystalline solids.
