A great deal can be learned by observing a sand box, and this delightful instructional resource offers ample proof. This resource was developed by Betsy D. Torrez of Sam Houston State University and it is designed to help students use sandbox models "to investigate the characteristics of normal faults and parameters that influence their development." The resource is intended for use by students in structural geology, and the site includes an overview of the context in which the activity should be used, along with a complete set of notes for instructors. Finally, the site also includes several student handouts and a list of supporting materials and references.
