Introductory Earth Science Collection
A good basic set containing 75 rock and mineral samples, unmounted, in a compartmentalized specimen tray. Rocks are number-coded to a list of their names by category with additional information contained in the accompanying Rocks and Minerals Study Guide. This set is used to demonstrate the major rock-forming minerals; the scale of hardness; and recognized physical properties (streak, luster, cleavage, fracture, and specific gravity). It also includes metal and nonmetal ores and igneous, sedimentary, and metamorphic rocks. Each specimen is of fairly good size (most about 1½" x ¾"). A streak plate, magnet, magnifier, nail, and copper coin are furnished so you can test for properties.
Enhance your geology study with these beautiful rock collections! Each kit contains 15 number-coded rock specimens, an information chart, and a key sheet for identification. Rocks are displayed in a sturdy, compartmentalized plastic tray. Some of the rocks include schist, quartzite, marble (metamorphic), shale, sandstone, limestone (sedimentary), and granite, porphyry, and scoria (igneous). Each rock is approximately 1 ½ x 1 ½ inches.
