Much more than just a crystal growing kit, this experiment kit teaches the chemistry of crystals and the geological science behind rock formation with more than 18 hands-on projects and investigations. Grow three chemically different types of crystals and build 3-D 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 using real specimens included in the kit. Conduct tests to determine 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. Includes a 32-page experiment manual.WARNING: Choking Hazard. Small Parts. Not for children under 3 yrs.
