Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: Learning About the Eyes, Ears, and Skin

*To improve your MATH SKILLS spend at least 20 minutes practicing them using IXL.COM. (REMEMBER TO ENTER YOUR USER NAME AND PASSWORD WHEN LOGGING ON! THAT WILL BE PROOF THAT YOU DID IT!)

Level#1

Light enters the eye through a clear, curved covering called the cornea. Behind the cornea is a colored part called the iris. The iris surrounds an opening in the eye called the pupil. The pupil allows light to enter the eye. The ears are the organs of hearing. They detect sound. The ear is divided into three sections: The outer ear, the middle ear, and the inner ear. Skin is the sense organ of touch. It can sense heat, cold, pressure, and pain. Some parts of your skin can sense touch better than others. Your finger tips have many more sensory neurons than your arms do.

1. What part of the eye does light enter through, and what is found behind it?






2. How many sections is the ear divided into, and what is each one called?






3. What is the skin the organ of?








Level#2

Light enters the eye through a clear, curved covering called the cornea. Behind the cornea is a colored part called the iris. The iris surrounds an opening in the eye called the pupil. The pupil allows light to enter the eye. Once light enters your eye, it passes through the lens. The lens is clear. It bends light rays so that they correctly hit the retina. The retina is the layer of sensory neurons at the back of your eye. It can sense brightness and color. The ears are the organs of hearing. They detect sound. The ear is divided into three sections: The outer ear, the middle ear, and the inner ear. Sound waves enter the outer ear and travel through the ear canal. The waves pass into the middle ear through the ear drum. the eardrum is a thin layer of tissue. When sound hits the eardrum, it vibrates. The vibration travels through small bones in the inner ear. Then, sound travels to the brain through nerves. Skin is the sense organ of touch. It can sense heat, cold, pressure, and pain. Some parts of your skin can sense touch better than others. Your finger tips have many more sensory neurons than your arms do. 

1. What is the retina and what can it sense?







2. What does the eardrum do when sound hits it, and what happens next?








3. What can the skin do, and what do your finger tips have more of than your arms?










Level#3

Light enters the eye through a clear, curved covering called the cornea. Behind the cornea is a colored part called the iris. The iris surrounds an opening in the eye called the pupil. The pupil allows light to enter the eye. Once light enters your eye, it passes through the lens. The lens is clear. It bends light rays so that they correctly hit the retina. The retina is the layer of sensory neurons at the back of your eye. It can sense brightness and color. The retina is attached to a thick bundle of nerves. The nerves carry the information to your brain. Your brain then makes sense of the information and you see a picture. The ears are the organs of hearing. They detect sound. The ear is divided into three sections: The outer ear, the middle ear, and the inner ear. Sound waves enter the outer ear and travel through the ear canal. The waves pass into the middle ear through the ear drum. the eardrum is a thin layer of tissue. When sound hits the eardrum, it vibrates. The vibration travels through small bones in the inner ear. Then, sound travels to the brain through nerves. Your ears also help to maintain your balance. There are three looped tubes in your inner ear. They are filled with liquid. As the liquid moves, receptor cells send information about balance to your brain. Skin is the sense organ of touch. It can sense heat, cold, pressure, and pain. Some parts of your skin can sense touch better than others. Your finger tips have many more sensory neurons than your arms do. 

1. Explain what the retina is, what it can do, and what happens to the information that the retina senses.








2. Besides hearing, explain the other important job that the ears do, and how they do it.


    







3. Explain what the skin can sense, what some parts of your skin can do better than others, and what do your finger tips have many more of than your arms do.
