KONOS Eyes & Seeing Vocabulary

You can "see" what we're working on today below... lots of fun vocabulary words and the KONOS eyes/seeing unit.

I thought I would drop in to leave you with our words and a lovely photo of Morgan's Iris. She has the most lovely eyes. The brown "spot" in her eye is called a nevus. It is similar to a birthmark. One in a million of those with an iris nevus contract cancer from them. I'm praying she won't. What is interesting is that she has her father's (and my mother's) topaz blue... and the spot is almost exactly the same color as my eyes (an orange-chestnut brown). I like to joke that the spot is my "only claim on her" or my "little piece of her" (since she looks so much like my mom and my husband). It has been fun studying the eyes, painting, vision, etc. I only wish I could have afforded the paints and canvases to let them do a rendition of their favorite painting! We will save and do that this summer, I hope. It will be moving to the "to do later" list. I'm anxious to start "Other Senses" and "Frontiersmen" soon!

We left a few words that were suggested out and added one or two of our own, so if you are a KONOS user, you might also check your Volume 1 to make sure you don't want to add any of the ones we skipped back in. We are doing a crossword and writing them in sentences today. Usually I make them write the definitions, but with lengthy medical terms... I am exercising some mercy!

The kids already know about diabetic retinopathy. Their grandma has it. We went with her to the doctor when she had a few of her appointments, and the kids went with me to the hospital when she had her eyes cut open, worked on and drained (a couple of years ago). Sounds gross, eh? It didn't feel good, either, so I hear! Imagine - stitches in your EYES! She was blind and now she can see. Sounds like another lost girl I know really well (metaphorically speaking, anyway).
