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.
Other Identifying Characteristics [edit]. Minerals have some other properties that can be used to identify them. For example, a mineral's crystal structure can be used to help identify the mineral. Sometimes, a trained mineralogist can tell the crystal structure just by looking at the shape of the mineral. mineral is more likely to break where the bonds between the atoms are weaker. Cleavage is the tendency of a mineral to break along certain planes to make smooth surfaces. Minerals with different crystal structures will cleave in different ways, as Figure 3.16 shows.
