Make A Frog Sandwich
     
     
     

Frog Anatomy

In this section, students will learn about frogs' skeletal, digestive, circulatory, respiratory and reproductive systems. In doing so, students will compare frog systems to human systems. And, because frog skin is very specialized for the environments in which they live, an activity on skin permeability is also included.

This lesson includes the following activities:

• Make a Frog Sandwich, in which students learn, label or draw frogs' skeletal, digestive, respiratory, urinary and reproductive systems.
  
  
• Frog Dissection, in which students dissect a real or virtual frog. Note: when you print the transparencies, you need to copy them onto transparency paper.
  
  
• Osmosis and Diffusion, in which students perform an experiment designed to illustrate how frogs breathe and drink through their skin.
  
  
• Big Picture Questions, in which students tie it all together by comparing frog anatomy, form and function to that of humans, looking for similarities, differences and possible connections.
