Warm-Up:
• List the 5 characteristics of a mineral.
![Page 2: Warm-Up: List the 5 characteristics of a mineral](https://reader033.vdocuments.site/reader033/viewer/2022051009/5a4d1b697f8b9ab0599b2880/html5/thumbnails/2.jpg)
Topic Objectives
• Identify the 5 properties of a mineral.
• Identify a mineral using its properties.
• Describe why color is not a good way to identify a mineral.

Mineral Properties
![Page 4: Warm-Up: List the 5 characteristics of a mineral](https://reader033.vdocuments.site/reader033/viewer/2022051009/5a4d1b697f8b9ab0599b2880/html5/thumbnails/4.jpg)
What are mineral properties?
• They are characteristics about specific types of minerals…ex. hematite is red and sulfur is yellow

Why should we care about mineral properties?
• Many minerals look the same, so if a scientist needs to identify a mineral, they must test its properties to figure out which type of mineral it is.

What are the 5 properties we will study?
1. Color
2. Luster
3. Streak
4. Hardness
5. Crystal Structure

Property #1: Color
• You can determine the color of a mineral by looking at it (Duh!), but make sure you are specific!
What color are the minerals below (specifically)?
![Page 8: Warm-Up: List the 5 characteristics of a mineral](https://reader033.vdocuments.site/reader033/viewer/2022051009/5a4d1b697f8b9ab0599b2880/html5/thumbnails/8.jpg)
Why is knowing the color not enough information to identify the mineral?
• Problem #1- Many different types of minerals have the same color…(milky quartz and calcite)
• Problem #2- One type of mineral can come in many different colors… (ex. quartz)

Property #2: Luster
• The luster of a mineral is the way that the mineral shines in light.
• Metallic Luster: Shines like polished metal
• Nonmetallic Luster: Does not shine like polished metal (can look glassy, earthy, oily, dull, etc.)

Property #3- Streak• The streak of a
mineral is the color of a mineral’s powder.
• This is determined using streak plates that gently scratch the mineral to turn some of it to powder.

Property #4- Hardness
• The hardness of a mineral is its resistance to being scratched.
1. Which mineral can scratch topaz, but not diamond?
2. Which mineral can only scratch talc?
3. Which mineral can scratch diamond?

Property #5- Crystal Structure
• The atoms in minerals are arranged into orderly structures (specific shapes).
- Cubic- Tetragonal- Orthrohombic- Hexagonal
![Page 13: Warm-Up: List the 5 characteristics of a mineral](https://reader033.vdocuments.site/reader033/viewer/2022051009/5a4d1b697f8b9ab0599b2880/html5/thumbnails/13.jpg)
Cubic
• Three axes (x, y, z) of equal length.
![Page 14: Warm-Up: List the 5 characteristics of a mineral](https://reader033.vdocuments.site/reader033/viewer/2022051009/5a4d1b697f8b9ab0599b2880/html5/thumbnails/14.jpg)
Tetragonal
• Three axes (x, y, z), with two of equal length and one of different length.
![Page 15: Warm-Up: List the 5 characteristics of a mineral](https://reader033.vdocuments.site/reader033/viewer/2022051009/5a4d1b697f8b9ab0599b2880/html5/thumbnails/15.jpg)
Orthrohombic
• Three axes (x, y, z), all of different length.
![Page 16: Warm-Up: List the 5 characteristics of a mineral](https://reader033.vdocuments.site/reader033/viewer/2022051009/5a4d1b697f8b9ab0599b2880/html5/thumbnails/16.jpg)
Hexagonal
• Three axes of equal length, one of different length (4 axes total!=6-sided).
