Autumn Leaves - Fun Facts: Learn about Why Leaves Change Colors in Autumn --- a site created by a girl named Tasha and her mother. Note: I usually don't use site with advertising banners and "pop ups", however this site is not only outstanding, but it was created by a second grader, so I chose to use it in spite of the advertising and use the advertisements as a teaching tool for students.
