Cow Eye Dissection!

We ended the 2010-2011 school year with the cow eye dissecti0n – one of the most fun and interesting (and sometimes gross!) lessons of the year. Each mentor led several children through the steps of the dissection, with the ultimate goal being to find the lens of the eye.

We removed the sclera, or the outer covering, and the cloudy cornea, to see the muscles of the eye. It was interesting to learn that although cows have a very wide field of vision, their eye can only move in four directions – up, down, left, and right. Cows can’t roll their eyes like humans!

After cutting through the cornea, we reached the back half of the eye and found the pupil, the iris, and the shiny lens of the eye!

Check out pictures from this year’s dissection – but be warned if you’re squeamish!
