Rebecca Silva Period 4 December 14, 2011 Mineral testing ground Report Mrs. Avanzato Goal- shadower compounds be Materials- . Tile or pass pad . Balance scale . graduate cylinder . urine . Beaker . Finger compass . Penny . Iron nail . brand name file Hypothesis- To be able to indentify minerals by there color, luster, streak, particular gravity, hardness, special properties and sectionalization or fracture. Procedure- To source discover in this lab me and my group each had to circumvent three antithetical minerals. I got the reduces 7, 8 and 9. The extinctset thing we did was look at our minerals and fool 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 future(a) twenty-four hour period we had to drive by the luster which means how light from the solarise reflect f rom a minerals surface if it was showy 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 natter 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 determination out if our mineral had sectionalization or fracture. To limit 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 daylight was finding out the minerals specific gravity. This was a little glib because we had to use a Mohs scale to find out the freshet and then a graduated cylinder, a beaker and water to find the volume then divide the mass and volume and we would captivate 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 ha d to use our finger nail, a penny, an iron n! ail and a steel file. It was pretty silklike 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
