Among the many resources on this site you will find their list of America's 11 most endangered historic places, "an annual list that highlights important examples of the nation's architectural, cultural and natural heritage that are at risk for destruction or irreparable damage."
Included on this year's list is Sumner Elementary School in Topeka, KS, one of the schools at the center of the U.S. Supreme Court's 1954 ruling in Brown v. Board of Education.
Even better-- there is a list of what you (and your students) can do to help! In the case of Sumner Elementary School, there is a link to a petition with sample text that can be edited and sent to the Topeka City Council.
Another site on the 2008 list is the Great Falls Portage, one of the best preserved areas on the Lewis & Clark expedition.
Take a look at the Issues page to see a list of other areas of concern including historic schools and public lands that are endangered.
Your students can write a REAL letter that might make a difference in a cause that they care about and want to support.
Here in Monroe County we are trying to preserve the River Raisin Battlefield, made famous in the War of 1812. Recently an abandoned factory built on the site was torn down, and now there is a study underway to see if this area can be designated as a national park.
What are the historic places in your area that should be preserved, and how can your students make a difference?
