Frog Dissection Pre-Lab

This document provides instructions and questions for a frog dissection pre-lab. It begins by listing the scientific classifications of frogs and defines some key anatomical terms like dorsal, ventral, anterior, and posterior. It then asks questions about frog adaptations, the differences between tadpoles and frogs, and how frogs' thin, moist skin and poorly developed lungs relate to their ability to live both on land and in water. The document instructs students to identify frog organs and their functions using an external website and encourages critical thinking about why frogs produce many eggs and why their tongues are anchored differently than humans.
