Rebecca Silva Period 4 December 14, 2011 Mineral research lab Report Mrs. Avanzato Goal- shadower compounds be Materials- . Tile or hunt pad . Balance scale . graduate cylinder . water . Beaker . Finger compass . Penny . Iron nail . nerve file Hypothesis- To be able to indentify minerals by there color, luster, streak, particularised gravity, hardness, special properties and sectionalization or fracture. Procedure- To source discover in this lab me and my group each had to circumvent three variant minerals. I got the reduces 7, 8 and 9. The extinctset thing we did was look at our minerals and stop what color they were. 7 was light green, 8 was white and 9 was olive green. We whence distributed our color to everybody else in the group. The beside twenty-four hour period we had to drive by the luster which means how light from the sunlight reflect from a miner als surface if it was glassy it was met all toldic if it wasnt it was non-metallic. When I held up my minerals to the light they were non-metallic. The next thing we had through was gain what color streak the mineral had. We took a streak plate and so scratched the mineral on it. Mine came out to 7-gray, 8-white and 9-white.
The fourth part of the lab was decision out if our mineral had sectionalization or fracture. To envision we had to see the way the mineral would break apart. My minerals all had something different. 7 had cleavage one, 8 has cleavage three and 9 had fracture. The next daytime was finding ou t the minerals specific gravity. This was a ! little sleek because we had to use a Mohs scale to find out the potbelly and then a graduated cylinder, a beaker and water to find the volume then divide the mass and volume and we would seize the density. My minerals all got a different gravity 7 was 2.8, 8 was 2.7 and 9 was 2.8. To find the hardness we had to use our finger nail, a penny, an iron nail and a steel file. It was pretty knavish because many of the minerals all broke of with many things. Number 7 was a three, number 8 was a...If you want to get a full essay, point it on our website: OrderCustomPaper.com
