As our class is presently studying expository writings, one of our students found herself enjoying the book Wildfires by Seymour Simon.  She became particularly interested in the fires of Yellowstone National Park.  This led her into some research on the size of the park, the percent which was affected by the 1988 fires, and the impact on the vegetation and wildlife.  Excited with her new found information, she volunteered to share with her classmates.  How interesting!
