Unit 1 Assignment: Rocks and Mineral Identification by Characteristics:
Proper identification of rocks and minerals is an important part of Earth Science. The goal of this assignment is to understand the major tests to identify each rock or mineral and apply what you learned to four examples. Using Microsoft PowerPoint, create a presentation addressing the following:
Introduce rock and mineral identification as a process. Make sure to include:
The difference between a rock and a mineral
Importance of proper identification
2. Using the list of identification tests for rocks and minerals, create a slide for each test with the following items:
How the test is performed (include equipment, images of equipment)
Examples of potential test outcomes (pictures encouraged)
Describe what each outcome means in terms of the rock and or mineral (e.g. does it indicate the presence of a specific type of chemical?)
3. After this series of slides, create a table with all the tests you presented and input the results for the following examples: Diamond, Dolomite, Gneiss, and Chalk. After your table, summarize the key characteristics of each sample that help in identification.
NOTE: Assignments will also be assessed on how well the presentation is made and accessible for the viewer to understand. This includes:
Clarity of information presented
APA formatting of citations (both on slides and at the end) (all images used must have a citation on the slide with the image)
Visual layout of information that engages the viewer
Mineral Tests:
Luster
Color
Streak
Light Transmission
Crystal Shape/Habit
Hardness
Cleavage
Fracture
Tenacity
Density
Rock Tests
