4-15-2010 FINISHED!!!. There are 30 countries, hundreds of photos, Garmin™ maps and scientist biographies all linked as a website. See www.jennymarshall.com/products.htm.


This DVD is created for students, teachers, and laymen. Although all text and photographs are copyrighted in the Library of Congress by the authors, permission will be given to students to use the pictures and text in their research and their presentation of information in a classroom setting as long as credit is given to the authors. The format of "Rediscovery of the Elements" is a running text with full graphics, to give the student a vicarious trip to the mines, stream beds, hillsides, laboratories, universities, museums, geographical and geological settings, and communities and cultures of the discovery sites. We welcome questions and comments from educators and students. For persons wanting to actually visit these sites, full directions including Garmin™ maps and GPS coordinates are furnished. All information and graphics come directly from the primary sources. This decade-long project is now in its final year. Profits are to go to student scholarships and fellowships.
