B12 Observations Should Include: Color=black coal, green fluorite, red granite, or white/pink limestone Transmit=opaque, translucent, transparent Luster=brilliant, glassy, dull Crystal size=small · or large • Weight=heavy or light Use=what it is, or could be, used for Hard or soft Anything else you observe Report results to me and return all items

B12 Rank Procedure On blank lab book page put: Name, Hour, Date B12 Natural Resource Ranking Make a big 4 column table with 5 rows. Title columns Resource Name, Observations, Value Ranking (hi1-4), Reasons for Ranking B=coal, W=limestone, G=fluorite, R=granite Examine resources and discuss observations and rank order of each item with your group
