RETINA
PUPIL

10. HOW CAN WE SEE?
①Light enters the eye trough the pupil ②An image is made on the retina ③ The retina sends this information to our brain, and this is what we see.

11. HOW CAN WE SEE?
❸The retina sends this information to our brain, and this is what we see
❶Light enters the eye trough the pupil
❷An image is made on the retina

12. THE EARS : THE HEARING Our ears are the organs of hearing
Our ears have three parts: the outer ear, the middle ear and the inner ear
The outer part is the visible part.
In the middle ear there is the eardrum and there are three small bones.
The cochlea is in the inner ear.

13. THE EARS : THE HEARING

14. HOW CAN WE HEAR? ①Sounds waves enter through the outer ear
②The waves hit the eardrum and make it vibrate
③The vibrations make the liquid in the cochlea move and send signals to the brain
④The brain read the signals and tell us what we hear

15. HOW CAN WE HEAR?

16. THE NOSE : THE SMELL Our nose is the organ we use to smell
