A Cow's Eye!

Dissecting the cow's eye is perhaps my favorite dissection item.  The piglet is a close second.  I have enjoyed teaching my children biology with dissection for years now.  Tom Sawyer has been pressuring me to do a dissection each quarter this year.  I missed doing a dissection with them the first quarter, so I either have to do two this quarter or forgo my promise to him.  Perish the thought!  We are finishing up On the Shores of Silver Lake and have had many conversations around blindness and the blessings of sight.  I thought this would be the perfect time to start catching up by dissection of a cow's eye to give a hands on look at the eye.

We studied the eye and found the optic nerve on the bottom of the eye. Then we cut the cornea away from the eye. We also identified the iris and the pupil.

The children then studied the lens.  The lens can be put on a paper with printed words to show it's magnification powers.

Little Red Riding Hood was a bit grossed out at first but really got into it before long.

The eye is really very beautiful.  The kids got so much out of this lesson.  Goldilocks was our photographer today.  She was having nothing to do with wearing gloves and touching any of this lesson. LOL!

I am joining Friday Fun School!
