Earth Science Crystals, Rocks, and Minerals -
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. 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 specimens 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.
Full-color, 32-page experiment manual.
- Recommended Ages: 8 years & Up
- Kit includes the following genuine specimens: granite, limestone, basalt, marble, pumice, calcite, pyrite, quartz, hematite, bornite, fluorite, magnetite, and soapstone.
Different than other crystal kits . Only about a third of this kit is about growing crystals. Most of it is activities dealing with geology and the rock cycle. All of the experiments work fine if you follow the directions. There are three different chemicals included, for the purpose of growing three different crystal SHAPES. Most crystal growing kits just include alum crystals with colored dyes to make differently colored crystals, but not different shapes. This is not the "easiest" crystal growing kit... if you just want to grow crystals, this is perhaps not the kit for you. But, with this kit you might actually learn something about rocks and minerals, and crystals which are the building blocks of rocks and minerals, rather than just pouring a packet of powder into some hot water and waiting for crystals to form.
