Mineral Identification Lab Worksheet for 6th - 12th Grade | Lesson ... - Free Printable

It looks like you've uploaded a blank Mineral Identification Lab worksheet, which is typically used in earth science or geology classes to help students identify minerals based on their physical properties.

Since the image contains only the empty table with column headers and no data or specific task, I can't solve a problem from it directly. However, I can explain how this worksheet is generally used and what kind of tasks might be associated with it.

🔍 Purpose of the Mineral Identification Lab Worksheet

This lab is designed to help students identify unknown minerals using observable physical properties. Students test each mineral sample and record their observations in the table.

📋 Column Headers Explained

Here are the typical meanings of the columns:

1. # (Number) – The number assigned to each mineral sample.
2. Name – The actual name of the mineral (filled in after identification).
3. Color – The visible color of the mineral.
4. Luster – How light reflects off the surface (e.g., metallic, non-metallic, glassy, dull).
5. Hardness – Measured on the Mohs scale (1–10). Often tested by scratching with other materials.
6. Cleavage/Fracture – Cleavage = clean break along planes; Fracture = irregular break.
7. Streak – Color of the powder when rubbed on a streak plate (usually white porcelain).
8. Density/Specific Gravity – How heavy the mineral is compared to water.
9. Other Properties – Includes things like magnetism, effervescence (reaction with acid), taste, smell, etc.
10. Identified Mineral – Final conclusion based on all tests.

✔ How to Use This Worksheet (Step-by-Step Example)

Suppose you have 10 mineral samples labeled #1 to #10.

For each sample, perform these tests:

1. Observe the color → Record it.
2. Check luster → Is it shiny? Dull? Metallic?
3. Test hardness → Try scratching with fingernail (hardness ~2.5), copper penny (~3), glass (~5.5), etc.
4. Look for cleavage/fracture → Does it break cleanly? Or in an uneven way?
5. Test streak → Rub on streak plate and note color.
6. Measure density → Compare weight to volume.
7. Check other properties → E.g., does it react with vinegar? Is it magnetic?

Then, use a mineral identification key or chart to match your observations to known minerals.
