Smithsonian History Explorer
"Smithsonian's History Explorer was developed by the National Museum of American History in partnership with the Verizon Foundation to offer hundreds of free, innovative online resources for teaching and learning American history. The site is designed for use by K-12 teachers and students, afterschool program providers, families, and individuals interested in lifelong learning. History Explorer's resources focus on learning history by ""reading"" objects for the stories they hold about the nation and its many peoples. Learning activities feature artifacts selected from over 3 million items in the Museum's collections, and draw on the expertise of the Museum's renowned curatorial staff. "
