Created by the folks at the Science Education Resource Center (SERC) at Carleton College, the Earth Exploration Toolbook (EET) was created "to support access to and effective use of scientific datasets and analysis tools by the educational community." The chapters of the Toolbook provide educators step-by-step instructions for using Earth system science datasets and scientific analysis tools. Visitors may wish to begin by exploring the "How can I use the EET?" section. After this, they can click on the "Chapters in the EET" area and start using one of the resource's 43 chapters. Chapters include "Analyzing the Antarctic Ozone Hole," "Climate History from Deep Sea Sediments," and "Evidence for Plate Tectonics." Also, it is worth noting that the "Tools" area on the right-hand side of the page allows users to look for specific tools, such as online mapping, image analysis, and data portals.
