Minerals and gems can be beautiful, but did you know that many of the products you use today come from common minerals? Come join us and learn about common and not so common minerals. You will participate in hands-on activities and demonstrations while learning how and why minerals are different. See unusual properties of some minerals demonstrated— fluorescence, phosphorescence, radioactivity, pleochroism, and magnetism, among others. You will also learn about gemstones, including how gems are valued. As an optional experience, the instructor will lead a tour of the Tucson Mineral, Gem and Fossil Showcase. Participants attending the tour will be required to sign a waiver.
