Though previously mentioned in another post, the The Valley of the Shadow Project has a wide range of primary sources from newspapers, maps, letters, and statistics all available for use in the 7-12 classroom. Broken up chronologically into three periods, the Project archives two communities (Augusta County, Virginia and Franklin County, Pennsylvania) between the years of 1859 and 1870. A particularly good lesson plan by Alice Carter compares the impact and the development of the railroads in both counties using various articles from historical newspapers. The lesson provides a teacher with preselected articles, however, one may choose to either find newspaper accounts that reflect individual class interests or allow students to search for their own, using the newspaper indexes. One special note: teachers could extend the lesson and explore the impact of railroads during reconstruction.
