But what is protecting the inside of your eyes?
[Call on two volunteers to share their answers. Listen for the words pupil and
iris.]
Luckily, eyes can protect themselves with the help of the iris and
the pupil. Remember pupil has another meaning. What is the other
meaning of pupil?
[Call on a student to answer]
That’s right, pupil also means student. See the tiny black dot right in
the middle of the eye?
[Point to a pupil in the picture.]
This tiny black dot is a covered hole called the pupil. See the different
colors around these pupils?
[Point around to the various irises in the picture and name their color.]
This color ring around the pupil is called the iris.

Show image 2A-6: Diagram of eye
Let’s take a look at a picture of an eye. Say the different parts of the
eye as I point to them.
[Point to eyelid, eyelash, eyebrow, tear duct, pupil, and iris.]
Now with your partner, talk about each part of your eye and what it
does. For example, you can say, “My eyelids blink to keep my eyes
moist.”
[Allow one minute for students to talk. Then call on one student at a time to
name a part of the eye and its function.]
My eyelids blink to keep my eyes moist and to protect my eyes.
My eyelashes keep dirt away from my eyes.
