Introductory Rock Collection
This collection is great for all ages. The 15 specimens measure 1 ½ to 2 inches each, and there are 5 in each rock category - sedimentary, igneous, and metamorphic. Specimens include shale, breccia, sandstone, conglomerate, limestone, obsidian, granite, basalt, scoria, rhyolite, slate, marble, quartzite, gneiss, and schist. This is a solid starter kit for your rock hounds: all packaged in a divided storage box. ~ Donna
Provides a primary presentation of the basic rock types. Includes five each of igneous, sedimentary and metamorphic rocks, totaling 15 specimens, approximately 1 1/2" x 1 1/2". Includes key and charts.
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!
