Mineral ID Lab Report with samples-2-1 (1)

Geology Name: Mysterious Banana Slug Identifying Rock Forming Minerals with at home lab kits Lab Report Complete your responses in a color other than black or red . Part 1: Identifying Unknown Minerals 2. Lay out all of your rocks on a blank sheet of paper and take a photo. Submit your photo below . Insert Photo/Image here: 3. Find your six (6) mineral samples (the other samples are rocks, which are made up of multiple minerals), then take a photo with each of the minerals named according to the list below. Submit your photo below . o Magnetite 1

Identifying Rock Forming Minerals Lab Report Insert Photo/Image here: 4. Now that we know what we are working with, make some observations with your samples by completing the table below for each mineral. o What luster do you observe? Is the sample metallic or nonmetallic? o Perform a streak test by scratching the sample on the porcelain tile in your Mineral ID kit. Is the streak provided for that mineral dark or light?  o Next, scratch your sample along the glass plate in your Mineral ID kit. What is the hardness of the sample relative to glass - does it scratch glass or not? o Observe the edges of your sample. Can it be easily broken by hand? Does the sample break with cleavage or fracture? (Note the cleavage angle(s) if given.) o Use the attached Mineral Identification Chart (linked in the  Materials  section of the  Introduction on Canvas) to see if you chose the correct sample for each mineral. Were there any variants between what you observed/tested and what the chart says? Explain. o Use the Mineral Identification Chart to determine which type of mica you have. What characteristic is key for this identification? o Use the Mineral Identification Chart to determine which type of feldspar you have. What characteristic is key for this identification? Type your response here: Sample’s mineral name Luster ( Metallic or Nonmetallic? ) Streak Color ( Dark or Light? ) Hardness (does it scratch glass?) Cleavage or Fracture? Type Key Characteristic(s) for identification purposes Magnetite Metallic Dark Yes Fracture n/a Magnetic Pyrite Metallic Dark Yes Fracture n/a Cubic crystal, high density, brass color Mica Nonmetallic Light No Cleavage Muscovite Thin sheets Quartz Nonmetallic Light Yes Fracture n/a Hexagonal crystals Feldspar Nonmetallic Light No Fracture Pyroxene Color black/green Talc Nonmetallic Light No Fracture n/a Very soft 5. There are many more minerals in this world than we could physically obtain for your kit. To demonstrate this, observe and classify the (12) 2D mineral samples (A) - (L) on Canvas by 4

Identifying Rock Forming Minerals Lab Report completing the table below for each mineral. We have provided 3D model links and various videos on the different minerals in  Part 3: Additional Help  in case you get stuck or just want to dive deeper into studying any of these minerals!  o What luster do you observe? Is the sample metallic or nonmetallic? o Is the streak provided for that mineral dark or light? o What is the hardness of the sample relative to glass - does it scratch glass or not? o Does the sample break with cleavage or fracture? (Note the relative angle if it is given.) o Use the attached Mineral Identification Chart (linked in the  Materials  section of the  Introduction ) to name the mineral in the last column.   Sample Number Luster ( Metallic or Nonmetallic? ): Streak Color ( Dark or Light? ): Hardness: (does it scratch glass?)
