Every once in a while it's nice to find a fantastic site that has broad appeal to lots of age groups and lots of subject areas. This site is just such a site. The National Parks service haslocations of interest for any subject area: history, science, math, language arts, and all the rest.
The site features a login option that allows a learner to keep track of what they have done and create a virtual portfolio of what they have completed. Visitors are allowed to navigate around the various tools and use nearly everything that a registered user can.
One of my very favorite activities is the Abraham Lincoln Timeline which quizzes you about various events in Lincoln's life and follows him from birth to the White House and beyond.
