This summary exercise involves crystal system and point group identification and stereo diagram construction.
This exercise is designed for a mid/upper-level undergraduate geology course on the principles of mineralogy.
Skills and concepts that students must have mastered
Students should have knowledge of basic chemistry and of minerals equivalent to what they would learn in an introductory geology class.
How the activity is situated in the course
This activity is the 29th of 36 mineralogy exercises and is used towards the end of the course.
Content/concepts goals for this activity
- Be able to identify symmetry.
- Become familiar with the crystal systems and the 32 point groups and be able to assign crystals to the correct ones.
- Be able to construct stereo diagrams for crystals of different shapes.
Higher order thinking skills goals for this activity
- Describe real objects (crystals) with abstract concepts such as symmetry and stereo diagrams.
Other skills goals for this activity
Description of the activity/assignment
This summary exercise involves crystal system and point group identification and stereo diagram construction. Students are presented with 5 blocks and for each block they must determine it's point group and crystal system, make stereo diagrams showing all symmetry and faces, and draw the blocks by hand or with SHAPE and label the Miller Indices.
