Voyages provides educators with learning activities based on real data from the Sloan Digital Sky Survey (SDSS) (featured in the 11-30-1999 Scout Report). The student-led activities are designed for learners to progress from simple conceptual activities to advanced discovery-based projects in astronomy. Advanced students will develop the skills and knowledge to delve into the SDSS database on their own. In the For Educators drop-down menu at the top of the page, the "Plan Your Voyage" page is a good place to start. The page details how the activities are categorized as Preflight, Launch, and Expedition based on length (from one class period to one week or more), knowledge level, and difficulty. On the same page, the Models for Using SDSS Voyages Activities section gives examples of how to structure lessons using Voyages materials. In the same drop-down menu, readers can click "Activity Descriptions" for a list of all the Voyages activities and teacher guides by level. In the Hands-On drop-down menu, educators can click "Accessibility Resources" to find tools for teaching astronomy to students with visual impairments. In the same menu, teachers can click "SDSS Plates for Education" to request a physical plug plate previously used for an SDSS spectrographic survey, along with resources for how to incorporate it into classroom learning (the plates are not necessary for Voyages activities but provide a fun bonus for students). Educational materials are available in English and Spanish (readers can click the flags at the top of the page to toggle languages). The New Mexico-based Sloan Digital Sky Survey is currently in its fourth phase, supported in part by funding from the Alfred P. Sloan Foundation and the U.S. Department of Energy Office of Science.
