Understanding Crystal Symmetry via Gestures part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students use a small mirror to explore the meaning of mirror symmetry, and then use their hands to gesture mirror planes for a group of familiar objects. They also explore the rotational symmetry of a group of familiar objects, and then use their hands to gesture the rotational axes and rotation. Finally, they use gestures to show mirror and rotational symmetry of wooden crystal models.

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.

Primary Structures and Rotation part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students gesture the orientations of cross-bedded sandstones, and in particular the relationship between a single cross bed and the bed sets. They do this for photos of undeformed and deformed cross-bedding.

Using Gesture to Support Spatial Thinking part of Spatial Thinking Workbook:Teaching Activities
Kristin Gagnier, Johns Hopkins University
This activity highlights the value of gesture in communicating spatial information. It consists of two short exercises. In the first, students are asked to pair up and describe to their partner how to navigate from one place to another in their home town. In the second, a volunteer is asked to sit on his or her hands and describe how to tie a bow with a piece of ribbon. In the first exercise, students spontaneously gesture; in the second, the volunteer will very much want to gesture and may be unable to complete the task under the restriction given (sitting on hands).

Understanding Mineral Cleavage via Gestures part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students use gesture to convey information about mineral cleavage and the relationship between crystal structures and cleavage planes.

Gestures for Silicate Structures part of Spatial Thinking Workbook:Teaching Activities
Carol Ormand Ph.D., Carleton College
Students use gestures to show the structures of single and double chain silicate minerals, paying attention to where silica tetrahedra share oxygen ions and the relative positions of the tetrahedra.
