1 ROCK HOUND Study Guide DESCRIPTION: Students will prepare a chart that they will use to help them identify various rock and mineral specimens. They will then answer questions about the characteristics of these specimens. TEAM SIZE: 1 or 2 students APPROXIMATE TIME: 30 minutes THE COMPETITION: 1. Teams will will identify rock and mineral specimens and answer questions about them.. Teams will have 1 minute per station to answer 4 to 7 multiple choice or true/false questions. The only items they will be allowed to bring into the competition are two 5 x 7 cards. The rocks and minerals that competitors need to be familiar with are listed below: ROCKS basalt conglomerate bituminous coal gneiss granite limestone (fossil) marble obsidian pumice quartzite sandstone schist (garnet) scoria shale slate MINERALS: calcite copper feldspar (pink) quartz halite hematite quartz (crystal) graphite gypsum (satin-spar) kaolinite gypsum (selenite) quartz (chert) pyrite mica-biotite ) fluorite mica-muscovite quartz (milky) talc lepidolite galena Rock and mineral characteristic questions may be about their color, specific gravity, relative hardness, reaction to molar hydrochloric acid, shape, texture, etc. SCORING: Each question answered correctly will be worth 1 point. The contestant with the highest total score will be the winner. Ties will be broken using predetermined tiebreaker questions.
