Identifying Minerals
Chapter 3 Lesson 1
![Page 2: Identifying Minerals Chapter 3 Lesson 1. Big Ideas The properties of rocks and minerals reflect the processes that formed them. How to identify common.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649e695503460f94b66d5c/html5/thumbnails/2.jpg)
Big Ideas
• The properties of rocks and minerals reflect the processes that formed them.
• How to identify common rock-forming minerals (including quartz, calcite, feldspar, mica, and hornblende) and ore minerals using a table of diagnostic properties.

Here’s the story...
Glen and Lindy are both learning about minerals at school. Lindy tells Glen
that only scientists can identify the type of mineral a sample is. Glen tells Lindy that
she is wrong. He tells her that he can identify minerals by their hardness.
What do we need to investigate?

Key Vocabulary
• Mohs' hardness scale - shows the hardness of a few common minerals.
• Hardness - a property that refers to a mineral’s ability to scratch or be scratched by another mineral.
• Minerals - natural, nonliving substances that make up rocks.

Focus Question:
• How can hardness be used to identify minerals?

Prediction:
• I think that we (will or will not) be able to identify the different minerals because......

Kit Inventory:
• Mineral samples
• Penny
• Iron nail
• Finger nail
![Page 8: Identifying Minerals Chapter 3 Lesson 1. Big Ideas The properties of rocks and minerals reflect the processes that formed them. How to identify common.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649e695503460f94b66d5c/html5/thumbnails/8.jpg)
Plan:
•Step 1:Take sample one and scratch it with your fingernail, a penny, and an iron nail. Record your observations.
•Step 2: Use Mohs' hardness table on page 144 and the identification table on page 145 in science book to name the mineral.
•Step 3: Repeat steps one and two with the other samples.
