Grade 4: All's Wool That Ends Wool - Sheep Eye Dissection

Graland Lower School science teachers recently added a new project to elevate the Grade 4 unit on animal senses: a sheep’s eye dissection!
During this activity, students looked at the sheep's eye structure and compared them to human eyes, discovered its unique features, and considered how to help an animal survive in the wild. In addition, fourth graders located the sheep's pupil, iris, lens, and cornea. They learned that the sheep's rectangular pupil helps increase their peripheral vision, so they can look for predators while grazing. Students also discovered the "tapetum lucidum," an iridescent layer on the back of many animals' eyes that improves their night vision. If you ask a fourth grader, they will tell you this is why many animals have "laser eyes" when you shine a light on them at night! Excellent work, Grade 4 scientists!
