but your eyes are not hard like a gumball. They are squishy like a
gummy bear.[Show students how the gummy bear is squishy. Remind students that they
should not put their fingers in their eyes.] Show image 2A-4: Girl with eyes shut
This girl is blinking. Can you show me how you blink? You are blinking
when your eyelids come down and cover your eyeballs. Even when
you are not thinking about it, your eyes blink by themselves every few
seconds.Why do we need to blink?[Call on two students to share their answer.]
What are the hairs on your eyelids called?[Pause for students to answer.]

Say the word eyelashes. Your eyelashes help keep dirt out of your
eyes. And what are the hairs above your eyes called?[Point to the girl’s eyebrow.]
Say the word eyebrows. Your eyebrows help keep water and sweat
from dripping down into your eyes. Show image 2A-5: Tears
Tears come out of your tear ducts to protect your eyes, too. Have you
ever had tears in your eye because something, like dirt, got into it?
Tell your partner what happened.[Allow thirty seconds for students to talk. Call on two students to share.]
