This deluxe classroom collection of 50 number-coded unmounted 1" specimens is ideal for all earth science studies. Specimens include examples of igneous, sedimentary and metamorphic rocks, ores, and gemstones. Nine of the ten hardness levels from the Mohs scale of hardness are included (all but diamond, the hardest). A cardboard storage box with a compartmented tray and Rocks, Minerals and Gemstones: an Introductory Study Guide are included.
The 16-page Rocks, Minerals and Gemstones: an Introductory Study Guide has basic introductory information on many, but not all, of the rock and mineral specimens in this collection. It is organized into sections on mineral properties, metallic minerals, nonmetallic minerals, rock forming minerals, igneous rocks, sedimentary rocks, metamorphic rocks, and gemstones. It also has charts on the rock cycle and on classification of the three types of rocks.
Note: This kit contains galena, a source of lead. Skin contact with galena is not dangerous; however, to avoid potential digestion, always wash hands after handling.
