Beaker . Finger compass . Penny . Iron nail . blade file Hypothesis- To be able to indentify minerals by there color, luster, streak, specific gravity, hardness, special properties and sectionalization or fracture. Procedure- To source discover in this lab me and my group each had to circumvent three antithetic minerals. I got the reduces 7, 8 and 9. The extinctset thing we did was look at our minerals and retrieve 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 side by side(p) twenty-four hour period we had to drive by the luster which means how light from the lie reflect fro m a minerals surface if it was undimmed 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 dupe 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 partition or fracture. To begin 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 twenty-four hour period was finding out the minerals specific gravity. This was a little foxy because we had to use a Mohs scale to find out the business deal and then a graduated cylinder, a beaker and water to find the volume then divide the mass and volume and we would operate 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 har dness we had to use our finger nail, a penny! , an iron nail 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
