Learn about rocks and the minerals that form them. Dig deeper, and discover the fascinating crystal structures of these minerals. Much more than just a crystal growing kit, this experiment kit teaches you 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 that exhibit not only different colors, but also different crystal shapes.
• Build three-dimensional geometric models of common crystals 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 specimen 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.
