Crescent Public School's online resources include a document with a diagram of the anatomy of an earthworm. This document is provided by one of the instructors on campus and is accessible to the public.
The document is also a worksheet for students of the instructor's class to fill out with answers to specific questions. It begins with outlining an earthworm's exterior, labeling every part of the body from the anterior to the posterior. It continues on to diagramming a dissection, in which the interior of an earthworm is outlined and labeled. The section includes diagrams of the digestive, circulatory, reproductive, nervous and excretory systems, and it explains each labeled part in depth.
