Level#1
One of the most common ear problems is an ear infection. Ear infections are caused by bacteria or viruses. Most ear infections are not serious. They can be treated with medicine. other hearing problems are harder to cure. People can lose some or all of their hearing after listen to music that is too loud or working with loud machinery. Sometimes, babies are born with damaged ear parts. This damage can cause loss of hearing or even total deafness.
1. What are two ways that people can lose some or all of their hearing?
2. What are babies sometimes born with?
3. Sometimes babies are born with damaged ear parts, what can this damage cause?
Level#2

Sometimes, babies are born with damaged ear parts. This damage can cause loss of hearing or even total deafness. Operations can help, and so can hearing aids. One kind of hearing aid sends sounds directly to the inner ear. Another kind sends the sound waves through the skull bones just behind the ear. Then, the inner ear picks up the sound.
1. What what can be done to help a baby that is born with damaged ear parts?
2. How does one kind of hearing aid work to help a person hear?
3. How does the other kind of hearing aid work to allow a person to hear?

Some problems with the ear can disrupt a person's balance. For example, vertigo is the feeling of dizziness. It can occur when a person rises too quickly from a sitting position, which affects the fluid in the inner ear.
1. Explain how the two types of hearing aids described in the text work to allow a person to hear.
2. Explain what some problems with the ear can cause, and give an example of one such problem.
3. Explain when vertigo can occur and what it affects.

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 does the iris surround, and what does the pupil do?
2. What are the ears, and what do they do?
3. What do your fingertips have many more of than your arms do?
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.

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 pupil does, what the lens does, and what the retina is.
2. Explain what the eardrum is, what happens when sound hits the eardrum, and what other jobs your ear does.
3. Explain what your fingertips have more of, as compared to your arms.
