The Human Eye
Preschool/Kindergarten level

In this unit study we learned the parts of the human eye and what they do.  We also learned how the human eye works much in the same way as a camera.

The following four subjects are generally the same for each topic of study.  The remaining subjects, which change with each unit study are listed below.  I have also repeated any subjects that have an added idea for this particular topic of study.

 

Reading: Read articles and borrow books from the library on the topic of study.  We also read stories daily/nightly, and we read the Bible. 
Phonics:

Right now, I mainly use file folder games using phonics flash cards as the skill cards in the game, and I also make skill cards for review of what we've learned.

Writing: Practice writing vocabulary words and upper and lower case alphabet.  I use a dotted font to make the words/letters on a lined paper and the kids trace them and then write them.
Music and 
Geography:
Using the Animaniacs song, "America" we learn about the states and capitals.  We try to learn 1 or 2 lines of the song each week.

I have also made a States & Capitals Memory Game to drill the states we have learned.

Vocabulary/
Spelling:

Iris, Cornea, Lens, Pupil, Retina

Math: We used "Wilbur" to practice math facts.
Science: Discuss how the eye works like a camera.  Look at our eyes in a mirror and discuss the visible parts.  Using a flashlight, see how the iris opens and closes to make the pupil bigger/smaller to let in more light, or block some light.
Social Studies: Discuss the quality of eye care in different countries, and how much that differs from the eye care we can receive here in the United States.
Geography: Find the countries discussed on a world map.
History: Find articles/books on early eye care, or on some of the earlier eye care tools/machines.
Craft:

We decided to make "Wilbur" this week.  We used a cleaned out bleach bottle and laid it on it's side.  Using the cup part of an egg carton, we cut out 4 to make the legs.  We used pink felt for the ears and "googly" eyes, and a pipe cleaner for the curly tail.  Across the back, just behind the ears, we cut a slot that went about half way through the bottle and was about 1/4 inch wide.  That would hold the large index cards (approx. 5 x 8) that I used to make the problems/answers.  I made the cards so that when inserted in the slot, the problem would show above the slot, and the kids would need to unscrew the cap (which is the pig's nose) and look inside to see the answer.

Field Trip:

We went to visit my eye doctor who showed the kids a working model of the human eye and went over the parts of the eye and how they work.  He explained how the retina receives the image upside down and when that image is sent to the brain, it is turned right-side up again.
