This document discusses the 5 human senses - sight, hearing, smell, taste, and touch. It identifies the sense organ associated with each sense and provides more detailed information about how the eye and ear work. The eye uses light to form an image on the retina, which sends signals to the brain to interpret vision. The ear uses sound waves hitting the eardrum and moving liquid in the inner ear to send signals to the brain to understand sounds.

1. Light reflects off an object and enter
through the pupil
2. The light goes through the lens and makes
an image in the retina

6. 3. The retina sends the information to
the brain
4. The brain reads the signals and tells
us what you can see.

8. 1. The sound waves enter through the outer
ear.
2. The waves hit the eardrum in the middle ear
3. This makes the liquid in the inner ear move
and send signals to the brain
4. The brain reads the signals and tell us what
you can hear.
