Product Description   Grow three chemically different types of crystals that exhibit not only different colors, but also different shapes. Build three-dimensional geometric models of common crystal shapes including octahedrons, tetrahedrons, and rhomboids. Mold your own crystal geode — a hollow rock with crystals growing inside! Learn how to test and identify minerals with your very own collection of real specimens included in the kit. Conduct tests to determine a mineral’s chemical and physical properties such as color, luster, streak color, hardness, density, magnetic properties, and carbon, sulfur, or iron content. Investigate the geologic rock cycle and learn how the three main categories of rock — igneous, sedimentary, and metamorphic — are formed, altered, destroyed, and formed again. Full-color, 32-page experiment manual.
