Spatial thinking is critical to the analytical work of the geosciences. Navigating unfamiliar landscapes requires a keen understanding of the lay of the land, as does constructing a cross-section through deformed rocks. This set of thematic resources from the Science Education Resource Center at Carleton College provides teaching activities, visualizations, and print and online references for educators who wish to incorporate these ways of thinking into their classrooms. In the Teaching Activities area, visitors will find 33 different activities, including "Northwest Passage," which is an investigation of changes in polar regions using Google Earth. Visitors can also look through these activities by type, such as Field Activity or Writing Assignment. The Visualizations area includes data related to earthquakes, seafloor topography, and satellite images. Finally, visitors can subscribe to the spatial thinking email list, or browse through the list's archives.
