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.
Chemical sedimentary rocks are identified by identifying the mineral from which they are composed. In this lab there are four minerals that need to be identified-quartz, halite, gypsum and calcite.Quartz has a hardness of 7 and is very difficult to scratch, even with a good quality knife blade.lastic sedimentary rocks contain clasts. These are fragments or pieces of rock or minerals. The composition of clastic sedimentary rocks is divided into three types-clay/silt, sand and gravel. Clay and silt are less than 1/16 mm. These are not visible to the unaided eye.
