Dissection in Lab

Dissecting a frog is a common and important experience in introductory biology or anatomy. Although students may feel intimidated at the thought of dissecting an animal, the learning experience is often profound. Most frog dissection labs involve a basic identification procedure. Students are required to open the frog, identify the basic organs and systems of the frog, explore the anatomy of the animal, and fill out a short lab report to accompany the project. For the most part, dissection specimens are sterilized and safe, but it’s still very important to keep hands, eyes, and mouth free of the formaldehyde used to preserve the frogs for dissection.
