This worksheet provides instructions for dissecting a preserved earthworm. Students start with external anatomy, identifying structures like the clitellum, the setae, and the sperm ducts. Using dissecting scissors, students carefully expose the internal structures, like the crop, gizzard, and intestine. Worksheet has diagrams to label and questions related to the earthworm.
A virtual earthworm dissection is also available for classrooms without access to a lab.
