Teachers MINERAL HARDNESS TEST KIT - Mohs mineral hardness scale 1-9 (talc, selenite, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum) in a resealable bag with a key identifying the hardness of each mineral. The teachers version - large pieces and identified by affixed number. Teachers includes streak plate, glass plate and nail, and instructional booklet. Extra charge for diamond.

PROPERTIES OF MINERALS - ES-500 - 18 compartment boxed set that explores not only Mohs 1-9 but other Properties of Minerals. Minerals included are the 9 Mohs scale minerals mentioned above plus galena (heft, s.g.), magnetite (magnetism), calcite or ulexite with optical properties, mica (cleavage), barite, pyrite, halite (salt). Booklet with information. Streak plates, glass plate, magnet. Content may change. $45-$55 depending on content (plus s&h)
Earth Science Kit ES 200 and ES250 are both designed for the teacher in mind. Each kit contains 18 specimens in a compartmented box with photo identification, instructional booklet with detailed specimen and geology descriptions and explanations. How do the two kits differ? Basically, ES200 is your "traditional" mineral and rock kit that contains samples of common rock-forming minerals and the rocks that they form. ES250 is a little "less traditional". It also contains samples that talk about basic geology. But it also uses other minerals to talk about economic uses of minerals, or interesting properties and processes. For example, galena demonstrates luster and cleavage; malachite demonstrates streak; magnetite represents magnetism; the rock cycle of quartz to sandstone to quartzite, etc.
Earth Science Kit ES-200. MINERALS ROCK! Common minerals and the rocks they form. 18 specimens. 6 minerals: quartz, calcite, muscovite mica, hornblende, microcline feldspar, biotite mica. 4 sedimentary: conglomerate, fossil limestone, sandstone, shale. 4 igneous: granite, diorite (intrusive); obsidian, pumice (extrusive or volcanic). 4 metamorphic: quartzite, slate, mica schist, gneiss.
