Description of the activity/assignment
For this assignment you will need to take a "selfie" with an everyday product or item that contains a mineral. In our Class Discussion Blog you will POST YOUR PICTURE and write your mineral description. Be sure to also include IDENTIFICATION INFO in your post:
1. Mineral Name and Chemical Composition
2. Physical Properties (Hardness, Luster, Cleavage, etc.)
3. Which rocks and/or type of environment might this mineral be found in?
4. How is the mineral being used in the product?
Once a mineral has been identified by a student in your lab section you can NO longer choose/identify that mineral, SO the earlier you complete this assignment the easier it will be for you. You could take a picture of a rock like granite but you will still need to identify a specific mineral in that rock.

- Instructors Notes:
I personally use this assignment as extra credit for an exam. I use the assignment for my 100+ student introductory course and to make posting a picture less intimidating - I create a blog for each lab group of ~20 students. I use the blog feature provided through my university's Blackboard site. Similar features are available in other course management systems, like Moodle or Canvas.
