Happy St. Patrick's Day!!! Today we started our "Stalagtite and Stalagmite" Lab. Visit our class WIKI http://duncanscience9.wikispaces.com to post observations of the crystal growth over the next few weeks. We also worked on "Mineral Identification", using the properties of Color, Luster, Hardness, Cleavage, and Fracture to identify mineral unknowns.
