Description:

Hands-On Geological Science Experiments

Much more than just a crystal-growing kit, this experiment set teaches you the chemistry of crystals and the geological science behind rock formation. 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.

Through the activities, you'll learn how to test and identify minerals with your very own collection of real specimens supplied including granite, limestone, basalt, marble, pumice, calcite, pyrite, quartz, hematite, bornite, fluorite, magnetite, and soapstone. 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.

All activities are outlined in a full-color, 32-page experiment manual.

WARNING: This set contains chemicals that may be harmful if misused. Read cautions on individual containers carefully. Not to be used by children except under adult supervision
