| Ready for some geology? Students intensely worked to test 12 mineral specimens. Hoggatteers had to use the tools of the trade - fingernail, nose, a penny, a magnifying glass, a nail, a magnet, a streak plate, a drop of water, and a penlight - check the specimens for hardness, shape, streak, light, luster, cleavage, smell, and feel. I'm especially proud of the group of girls in the video above. Their communication of the concepts was spot-on, and they didn't even realize it. |
