Biology: Health and Dissections

One of Legoboy's August plans is to finish his study of human anatomy health (or come close to finishing). 

He selected the book "My Temple of the Holy Spirit" as his core resource, with "Blood and Guts" for follow-up. He is also using two anatomy "coloring books" (high school level) to read and color in as he learns about each area of the body. 

We added a couple of books on the development of unborn children to cover reproduction. 

This past week, he has been studying the brain, the sense organs and circulation as interest and focus strikes him. This morning (of the day I write this), he and I had a conversation about these topics, as something of an oral exam. He had his choice of styles of presentation of information to me: write about each area, create something in the area to show what he has learned, chat with me about it, or pick another adult with whom to chat. He chose chatting with Mama ;) Can't complain there! ;) 

As part of the brain topic, we looked at a model we had on hand; he identified the parts and function of what he knew and we looked up the rest. 

Repeated for the heart. We just happened to have both of these on hand. Not planned what-so-ever. 

But then he said, "Didn't we purchase a cow's eye from Home Science Tools?"

Why yes, Son, yes we did. 

Removing some of the fat. 

Removing the cornea

Removing the cornea

Cutting the eye in half (separating into posterior and anterior portions)

examining his collections
and generally looking handsome

specimens collected for examination under a microscope the next day
(stored in a ziplock bag overnight)

Removing the tapetum

beyond the instructions:
let's cut in half laterally!
He wanted to see the layers behind the eyeball

there they are

any one more, just in case you wanted to see it again ;)
