8th Grade
Today's theme was identifying minerals using physical characteristics.
Today in class we went over the difference between fracture and cleavage in minerals. Following this brief discussion (and a story about a meat cleaver) we broke into groups and went through six stations that demonstrated each physical characteristic used to ID minerals.
We touched on smell, taste, feel, chemical reactivity, radioactivity, optical properties, density, hardness, color, luster, magnetism and fluorescence.
