The Cay review

The cay is a book written in 1969 by Theodore Taylor about a group of people trying to flee to America from the island of Willemstad during WW2 however they are found by a german u-boat and their ship begins to sink only two people escape an old 70 something man named timothy and a young 12-year-old boy named Phillip together that they find themselves in a small raft drifting somewhere in the Caribbean eventually they drift to a small cay filled with langosta and palm trees. 

Overall I would rate this as a fairly good book with some good twists as well as making you wonder if they ever will get off the cay but the book was rather short at only 122 pages.

Scissors 

Method:

1. Get eye

4. Drain the vitreous humorous

5. Turn the eye inside out 

6. Cut into 3 equal parts 

Parts:

Sclera: white protective layer

cornea: sclera but at the front

Iris: color

pupil: lets in light

I enjoyed the dissection aside from the smell when we turned the eye inside out we saw the tapetum lucidum and had to move the retina to be able to fully see it
