Using live animals in the elementary science classroom fosters enthusiasm and encourages curiosity. The earthworms discussed in this article, commonly called night crawlers, are easy to find in Iowa in moist garden soil or around lawns. Earthworms are often used as fishing bait and, because of this, are readily available at reasonable prices from commercial bait dealers or backyard entrepreneurs. Besides their availability and low cost, earthworms are relatively hardy and easily handled by elementary students. For these reasons, and because of the very important role earthworms play in the environment, they were selected to be the focus of the academic activities for one day in first and second grade classrooms. These activities have been used successfully for the past four years.
