Grand Canyon National Park
Life on the Edge
 
Life on the Edge ecology program
Students will learn about the plants and animals living in Grand Canyon National Park as well as the adaptations that help them survive.
This is a five hour ecology program that focuses on interrelationships between living and non-living components in the Grand Canyon environment.  Students learn about biological and ecological concepts such as adaptations, niches, and life cycles through role-playing games and hands-on activities while walking along 1.5 miles of the canyon rim. The life of a Grand Canyon ecosystem is literally a "life on the edge."
