Educational worksheet for matching and classifying minerals and rocks.

Task Overview:

The worksheet involves two main tasks:
1. Matching Minerals and Rocks with Their Names.
2. Classifying the Minerals and Rocks as Hard or Soft.

Let's solve each part step by step.

Part 1: Matching Minerals and Rocks with Their Names

#### Step 1: Identify Each Mineral/Rock
We are given six images of minerals/rocks and six names to match them with:
- Graphite
- Gypsum
- Marble
- Granite
- Clay
- Diamond

#### Step 2: Match Each Image with the Correct Name
1. Image 1 (Shiny, transparent crystal):
- This is a Diamond. Diamonds are known for their transparency and high luster.
- Match: Diamond

2. Image 2 (Speckled, light-colored rock):
- This is Granite. Granite is a common igneous rock with visible speckles of quartz, feldspar, and mica.
- Match: Granite

3. Image 3 (Dark, shiny rock):
- This is Graphite. Graphite is a soft, black mineral often used in pencils due to its slippery texture.
- Match: Graphite

4. Image 4 (White, crystalline rock):
- This is Gypsum. Gypsum is a soft, white mineral that forms in layers and has a distinctive crystalline structure.
- Match: Gypsum

5. Image 5 (Light-colored, smooth rock):
- This is Marble. Marble is a metamorphic rock composed primarily of recrystallized carbonate minerals, giving it a smooth appearance.
- Match: Marble

6. Image 6 (Orange, rough rock):
- This is Clay. Clay is a fine-grained sedimentary material that is typically soft and can be molded when wet.
- Match: Clay

#### Final Matches:
- Image 1: Diamond
- Image 2: Granite
- Image 3: Graphite
- Image 4: Gypsum
- Image 5: Marble
- Image 6: Clay

Part 2: Classifying the Minerals and Rocks as Hard or Soft

#### Step 1: Understand Hardness
- Hard Minerals/Rocks: These are resistant to scratching or breaking. Examples include diamond, granite, and marble.
- Soft Minerals/Rocks: These are easily scratched or broken. Examples include graphite, gypsum, and clay.

#### Step 2: Classify Each Mineral/Rock
Using the matches from Part 1:
1. Diamond: Extremely hard (hardest natural mineral).
- Classification: Hard

2. Granite: Hard, composed of quartz, feldspar, and mica.
- Classification: Hard

3. Graphite: Very soft, used in pencils due to its slipperiness.
- Classification: Soft

4. Gypsum: Soft, can be scratched with a fingernail.
- Classification: Soft

5. Marble: Hard, though it can be polished and carved.
- Classification: Hard

6. Clay: Soft, easily molded when wet.
- Classification: Soft

#### Final Classification:
- Hard: Diamond, Granite, Marble
- Soft: Graphite, Gypsum, Clay

Final Answer

1. Matching:
- Image 1: Diamond
- Image 2: Granite
- Image 3: Graphite
- Image 4: Gypsum
- Image 5: Marble
- Image 6: Clay

2. Classification:
- Hard: Diamond, Granite, Marble
- Soft: Graphite, Gypsum, Clay

Boxed Final Answer:
\[
\boxed{
\text{Matching: } \text{Image 1: Diamond, Image 2: Granite, Image 3: Graphite, Image 4: Gypsum, Image 5: Marble, Image 6: Clay} \\
\text{Classification: } \text{Hard: Diamond, Granite, Marble; Soft: Graphite, Gypsum, Clay}
}
