Dissection Activity Models: Earthworm

Internal systems and organs of this low order invertebrate (Earthworm) are shown on this raised relief plaque. This model features a medial section of the anterior, as well as a cross-section, to illustrate all the important characteristics of an earthworm: the clitellum, complete segmentation, the anus, and all internal systems such as longitudinal muscles and the intestine. Includes a Teacher Activity Binder with lesson plans identifying 37 structures, copymasters for student activities and an overhead transparency.

Comments & References: Raised relief plaque. Measures 24 x 18 inches (approx. 61 x 46 cm). Made of high impact plastic reinforced with rigid foam. Suitable to use before dissection, to accompany a dissection, as a make up for a missed dissection, or as a practical after dissection. Please see Crayfish, Frog, Clam, Perch, Grasshopper and Fetal Pig for the other individual plaque models in this series. Please also see information on the Somso Earthworm Model and a YouTube earthworm video that explains the internal anatomy of an earthworm, using an earthworm model.
