Courtney's Reflection Post

This project was, to me, the most fun project we had all year, including other classes. I loved how I could express myself in the blog I made, and I could understand what I was doing. I don't dislike blogging at all, and I am looking forward to blogging next year. Blogging was a bit unusual at first, but after I learned it seemed pretty easy. Blogging is also very helpful for understanding what we did in class, and it helps with homework. As I said, blogging is very fun, and I am excited on blogging next year.

The eye!

On Wednesday 6th grade got to watch ms.d dissect a sheeps eye. While we were watching our teacher dissect, we saw the different parts of the eye, for example, we saw the lens, the vitreous, the optic nerve, and so on. It was interesting watching the eye being disected, the part that I saw, and it was very educational.      As you can see above this is a diagram of the eye.

Cornea - the clear, dome-shaped tissue covering the front of the eye.

Iris - the colored part of the eye - it controls the amount of light that enters the eye by changing the size of the pupil


Lens - a crystalline structure located just behind the iris - it focuses light onto the retina


Optic nerve - the nerve that transmits electrical impulses from the retina to the brain


Pupil - the opening in the center of the iris- it changes size as the amount of light changes (the more light, the smaller the hole) 

Retina - sensory tissue that lines the back of the eye. It contains millions of photoreceptors (rods and cones) that convert light rays into electrical impulses that are relayed to the brain via the optic nerve


Vitreous - a thick, transparent liquid that fills the center of the eye - it is mostly water and gives the eye its form and shape (also called the vitreous humor)

The eye is a definitively amazing organ and without it we would not be able to see, or to have a visible sense of direction.
I hope you liked my scribe!
6th grade, for homework we need to finish our lab, due on friday! Remember that tomorrow, Thursday, we are welcome to come in during lunch for a study session about the EMS, the light vocabulary, the parts of the eye and the differences between mirrors, prisms and lenses! Be sure to come in! 

Have a great day!

The next scribe is Ghazaleh.
