Objective:
To identify the minerals name by how it is.
Hypothesis:
My surmise is that mineral number 1 is watch glass because I pick come in that quartz minerals ar very hard. I also call that mineral number 4 is calcite because I know that calcite minerals the superman test is positive. I think that mineral number18 is chalk because chalks minerals are very soft that can be scratch with you aver finger settle. The last mineral number 20 I think is a marble because I know that marble the acid test is negative.
Material:
* Finger nail
* penny
* Silver nail
* churl
* Scale
* discharge table holder
* Test tube
* pane (vinegar)
* Graduried Cylinder
Procedure:
1. First, we assemble the shape, color, cleaver or feature by observing the mineral.
2. Second, we lay down the streak and luster by observing the luster, and then by touch the mineral dust.
3. Next, we found the hardness by scratching with finger nail, penny, silver nail, and a glass.
4. Then, we found three Acid by scratching the mineral and put the dust in the test tube and we put three drops of acid if bubbles came out it was positive but if it didnt came out bubbles it was negative.
5. The last thing we did is was that we found the Density by dividing the mineral mass and volume.
potation: Doing the Acid test

Analysis
The mineral number 1 is quartz because it is very hard, the hardness is 7, the...If you want to get a wide essay, order it on our website: Orderessay
