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 shapes. Build three-dimensional geometric models of common crystal shapes including octahedrons, tetrahedrons, and rhomboids.
