Thames & Kosmos 642112 Crystals, Rocks & Minerals Science Experiment Kit

Description

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!
