1000001: Rocks & Minerals Earth Science Collection, 75 specimens


This premium Earth Science collection of 75 number-coded, unmounted 3/4"-1" specimens is a valuable tool for demonstrating physical properties, the scale of hardness, and the major rock-forming minerals. Nine of the ten hardness levels from the Mohs scale are included. Sturdy compartmented storage box, streak plate, magnet, magnifier, and Rocks, Minerals and Gemstones: an Introductory Study Guide are included. Ages 12 & up.

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.

The following rocks and minerals are typically included in this set:
