Sketching Block Diagrams part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students watch a video of the instructor sketching two geologic block diagrams (of flat stratigraphy and of an upright anticline), then practice sketching additional geologic block diagrams.

Fault Separation part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students use gestures to explore the relationship between fault slip direction and fault separation by varying the geometry of faulted layers and the slip direction.

Folds and Cleavage part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students explore the geometric relationship between bedding/cleavage intersections and fold axes for axial planar, fanning, and transecting cleavage.

Restraining Bends and Releasing Bends part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students use gestures to re-create the motion of fault blocks adjacent to restraining bends and releasing bends. They then answer a few questions about a map view of the San Andreas Fault and two of its bends.

Contractional Strain part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students use gesture to describe the bulk deformation and local deformation apparent in images of a contractional analog experiment. Students then calculate bulk shortening and bulk thickening for the experiment and describe the structures accommodating that strain.
