Rocks and Minerals of U.S. Reference Collection (24 pcs.)
Much like the above collection, only with fewer specimens. The 35 or 24 rocks and minerals form a more abbreviated, but still adequate, range of materials for your study of geology or for identification/reference. Instead of buying one of those overpriced "book and skimpy rock collection" combo sets that pervade the market, settle on a good, basic book about rocks and rock-collecting, and use one of these sets as your samples. Unmount the specimens if you prefer - either way, you'll have a much larger and more complete collection for about the same price. Rocks in Basic set measure ½"-¾" while those in the Reference collection are slightly larger at ¾"-1". Study Guide included.
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.
We have several rock-hounds here - as evidenced by the boxes of rocks that haunt the dark recesses under beds and in closets, when they're not strewn all over the floor! Of course, our "good" rock collections don't suffer the same fate. These have been used countless times in our homeschool, especially in our study of Earth Science. Kept in the schoolroom, the children are free to use them to identify other rocks or just to peruse for sheer delight. I guess you can tell that I am rather fond of rocks myself. The combinations and varieties that God has embedded in the Earth are astounding and beautiful. We had to "dig" a little for the information to stock these, but it was totally worth the effort!
