3. EYEBALL -10
What is the name of the dark pigmented back layer of the eyeball? (where specialized cells are located and where the image is formed)

4. EYEBALL -10
ANSWER
RETINA

5. Name is based on shape of cells
EYEBALL -20
The retina has two specialized cells that help interpret and understand light… what are those cells called?
Name is based on shape of cells

7. How does the eye control the amount of light that enters?
EYEBALL - 30
How does the eye control the amount of light that enters?
Example entering a dark room we need to let more light in… going outside into bright light we need to reduce the amount that enters our eye... Explain how this works

8. EYEBALL -30
ANSWER
The IRIS (colourful part of the eye) will expand or contract making the PUPIL smaller or larger.
In a dark room the pupil (hole in the eye) will open up to let as much light in as possible
In bright lights the pupil gets very small reducing light intake

9. What is Aqueous Humor and Vitreous Humor in the eye?
EYEBALL - 40
What is Aqueous Humor and Vitreous Humor in the eye?
Define and describe…

10. EYEBALL - 40
ANSWER
Aqueous Humor is the liquid that fills the space between the CORNEA and the IRIS/PUPIL
Vitreous Humor is the Gel-like liquid that fills the space between the LENS and the RETINA of the eye
Both liquids help the eye keep its shape
Some protection and shock absorption properties also

12. EYEBALL - 50
ANSWER
The Brain will flip images right way up

23. Bending/bouncing -10
When light travels from one medium to another (example air to water) what happens to the light rays?

24. Bending/bouncing -10
ANSWER:
REFRACTION: Light bends (changes direction slightly due to changing speed when hitting a different medium)
