Slicing Cylinders part of Spatial Thinking Workbook:Teaching Activities
Students identify and draw slices through cylinders and partial cylinders, and use gestures to visualize slicing planes. This practice with visualizing slices through idealized geometric shapes is preparation for visualizing slices through geological features.

Slicing Fruit part of Spatial Thinking Workbook:Teaching Activities
Students identify and draw slices through fruit, as practice for drawing slices through more complex features.

Slices Through 3D Objects part of Spatial Thinking Workbook:Teaching Activities
Students identify and draw slices through an ice cream cone, a pyramid, and a beverage six-pack.

Sketching Block Diagrams part of Spatial Thinking Workbook:Teaching Activities
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.

Introduction to 3D Sketching part of Spatial Thinking Workbook:Teaching Activities
This activity provides an introduction to 3D sketching. Students sketch a cube, boxes, and cylinders. They watch a video about how to sketch boxes and cylinders, and then sketch a few more.

Understanding Polyhedral Diagrams part of Spatial Thinking Workbook:Teaching Activities
Students identify individual polyhedra in a variety of diagrams and answer questions about shared oxygens in diagrams of common silicate structures.

Contractional Strain part of Spatial Thinking Workbook:Teaching Activities
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.

Slicing Rocks part of Spatial Thinking Workbook:Teaching Activities
Students examine images of a bowl of rocks, then several rock piles, then outcrops of conglomerate and breccia. They sketch slices through the bowl of rocks, match photos of rock piles to sketches of slices through those piles, and then apply what they've learned to describe the conglomerate and breccia.

Slicing Fossils part of Spatial Thinking Workbook:Teaching Activities
Students examine images of brachiopods, mollusks, and coquinas. They identify, visualize, and sketch slices through a variety of shelly organisms, then apply what they've learned to identify fossils in several samples of coquina.

Deciphering Mineral Structure Diagrams part of Spatial Thinking Workbook:Teaching Activities
Students compare mineral structures shown in ball-and-stick, space filling, and polyhedral diagrams.
