We had so much fun today learning about our eyes! If you don’t know, my daughter and I are doing a learning unit on the human body. Initially I wasn’t even going to do anything with the eyes, other than paint them on the skin. However, my daughter had some cool eye ball chocolates left over from Halloween, and I thought they would go perfectly for a little eye unit… and after a few minutes of google searching we had some activities planned!
First, we talked about vocabulary. The sclera (white part of your eye), the pupil (black part which my daughter pronounces pwEEple- its so cute!), the iris (colored part), and the cornea (clear outer protective layer). We talked about how the eye is shaped like a ball or sphere. We looked at the blood vessels in our scleras. To learn more about the pupil, we did a short and easy science experiment. We got a mirror, dimmed the lights, and watched our pupils get bigger to let more light into our eyes. Then we turned on the lights and watched how quickly the size of our pupils was reduced. My daughter was AMAZED by this- we probably did it at least 15 times. After watching our pupils dilate, we talked about our iris. I asked her questions like “What color are daddy’s irises?” Then we talked about how the cornea is clear and it protects our eye. When we touch the inside of our eyes, we are touching the cornea. Later, when we were finishing up our eye unit Boo told me that we should never touch our corneas and then proceeded to have her human body chart guy touch her cornea. I guess we can tag this guy as a stinker!
After munching on eye ball Halloween candy and watching a short video on the human eye, we grabbed paper and started cutting out the different pieces to our eyes. Looking back- I would have made the iris with a whole in the middle and the pupil underneath, but we did it the easy way by just gluing the black circle on top of the iris. So not scientifically accurate, I know!! And we cut out circles from an old sheet protector to use as the corneas. My favorite part of the eye model, I must say.
Once the eyes were made, we started working on the skin. So far it looks SO CUTE! I am excited to post about it tomorrow!
