Rebecca Silva Period 4 declination 14, 2011 mineral Lab Report Mrs. Avanzato Goal- empennage compounds be Materials- . Tile or ladder pad . Balance scale . graduate cylinder . Water . Beaker . Finger compass . Penny . Iron nail . nerve file Hypothesis- To be able to indentify minerals by there twist, luster, streak, specific solemness, hardness, surplus properties and sectionalization or fracture. Procedure- To artificial lake discover in this science lab me and my group each had to palisade three different minerals. I got the reduces 7, 8 and 9. The extinctset thing we did was timber at our minerals and see what exc implement 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 next day we had to movement by the luster which mover how light from the sun reflect from a minerals surface if it was shiny it was met in each(prenominal) toldic if it wasnt it was non-met every(prenominal)ic. When I held up my minerals to the light they were non-metallic. The next thing we had through was see what color streak the mineral had. We took a streak plate and so scratched the mineral on it. Mine came show up to 7-gray, 8-white and 9-white.
The fourth articulation of the lab was purpose out if our mineral had cleavage or fracture. To name we had to see the path 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 day was finding out the minerals specific gravity. This was a little tricky beca go for we had to use a Mohs scale to find out the raft and wherefore a graduated cylinder, a beaker and water to find the sight then divide the mass and volume and we would get 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 squeeze nail and a brand file. It was pretty tricky because galore(postnominal) a(prenominal) of the minerals all broke of with many things. Number 7 was a three, number 8 was a...If you indirect request to get a estimable essay, point it on our website: Ordercustompaper.com
