In this STEM lesson, students will investigate and understand that adaptations allow animals to satisfy life needs and respond to the environment by designing their own pattern of animal coloration  (e.g., countershading camouflage) that might help an animal survive in its habitat. They will observe the physical adaptations of their class pet (e.g., fish or other animals) and consider how those features benefit the animal.  

This lesson can be easily adapted for other grades or pets.
