Cow Eyes
A  WebQuest for Grades 6 - 8, WebQuest Agricultural Series by Missouri Farm Bureau and Missouri State University



INTRODUCTION
Have you ever wondered what is inside your eye?  When  you look in the mirror or at a friend, you see the outer part of the eye.  What are those parts called and what is beyond (behind) what we see?  Through this WebQuest you will learn about the human eye and its functions.  To understand what is inside your eye and how it works we will also examine a cow's eye and virtually dissect it.  A cow's eye has many similarities to a human eye and you will discover those similarities and differences.


OVERALL TASK
