Cow Eye Dissection

worksheetStudents dissect a cow eye as part of a unit on anatomy or the senses.  This guide contains step by step instructions on how to cut the eye and identify the major features, such as the cornea, sclera, retina, vitreous humor, lens, and optic nerve.  The dissection is very simple and can easily be conducted with younger students, though I would suggest using scissors instead of a scalpel with younger students.

The worksheet also contains questions and a labeling exercise. Students will need other resources, like a textbook or google to label the drawing.

Students are also asked to take a photo of their eye and upload to social media, though this is optional. My students do love sharing their photos with their friends and I enjoy seeing the pictures they share on twitter under the hashtag #coweye.

Cow eyes can be purchased from Carolina, through or purchased directly from biological supply companies.
