Hey there! Today, we’re going to explore the amazing world of the human ear. Our ears are super important because they help us hear sounds and keep our balance. Let’s dive in and learn how they work!
The ear is divided into three main parts: the outer ear, the middle ear, and the inner ear. Each part has a special job to do.
The outer ear is the part we can see. It has two main parts: the auricle and the auditory canal. The auricle is like a little satellite dish that catches sound waves, and the auditory canal is a tunnel that guides these sound waves to the middle ear.
In the middle ear, we have the eardrum and three tiny bones called the hammer, the incus, and the stirrup. These bones are super important because they help send sounds to the inner ear. The eardrum is like a drumhead that vibrates when sound waves hit it. This makes the tiny bones move, which makes the sound louder. There’s also something called the eustachian tubes that help keep the pressure in your ear just right.
The inner ear is where the magic happens! It has a special part called the cochlea, which looks like a snail shell. The cochlea turns the vibrations from the middle ear into signals that travel to the brain through the auditory nerve. The brain then understands these signals as sounds, like music or a friend’s voice.
Sound is made up of vibrations that move through the air like waves. These waves enter the ear through the auricle and travel down the ear canal. When they reach the eardrum, it starts to vibrate. This makes the tiny bones in the middle ear move, sending the sound waves to the cochlea. The cochlea changes these waves into signals that the brain can understand. That’s how we recognize different sounds, like a ringing phone or a barking dog!
It’s important to take good care of your ears. Try not to use earphones for more than an hour a day, and keep the volume low to protect your hearing.
And that’s how the human ear works! Isn’t it amazing how our ears help us hear the world around us? Keep exploring and learning more about the wonders of the human body!
Sound Wave Experiment: Create your own sound waves using a simple experiment. Fill a bowl with water and gently tap the surface with your finger. Watch how the water ripples. These ripples are like sound waves traveling through the air. Try tapping with different objects like a spoon or a pencil and observe how the ripples change. Discuss with a friend or family member how this is similar to how sound waves travel through the air to your ear.
Ear Model Craft: Make a model of the ear using craft materials. Use a paper plate to represent the outer ear, straws for the auditory canal, and small clay pieces for the tiny bones in the middle ear. Use a spiral-shaped pasta to represent the cochlea in the inner ear. Label each part and explain its function to someone at home. This will help you remember how each part of the ear works together to help us hear.
Sound Scavenger Hunt: Go on a sound scavenger hunt around your home or neighborhood. Make a list of different sounds you hear, like a bird chirping, a car honking, or leaves rustling. Try to identify which sounds are loud and which are soft. Think about how your ear helps you recognize these sounds. Share your list with a friend and see if they heard the same sounds.
Sure! Here’s a sanitized version of the transcript:

Smile and learn! Today we’re going to learn about the parts of the human ear.
[Music]
The ear is the organ that creates our sense of hearing and balance. This organ is in charge of capturing sounds around us and sending the signals to the brain so that it reacts accordingly. Imagine you hear an ambulance siren; your ear will signal the brain, which will then signal the muscles to move so you can walk away.
The ear is divided into three parts: the outer ear, the middle ear, and the inner ear. The outer ear is made up of two parts: the auricle, which captures sound waves, and the auditory canal, through which sound travels to reach the middle ear.

The middle ear is made up of the eardrum and three bones: the hammer, the incus, and the stirrup. These transmit sounds to the cochlea. The eustachian tubes are also located in the middle ear. The eardrum is a membrane similar to a drumhead and is located between the outer ear and the inner ear. When sounds reach the tympanic membrane, it starts vibrating and causes the tiny bones to move. The tiny bones, called hammer, incus, and stirrup, start moving, which amplifies the vibrations transmitted by the eardrum. Then, the bones send the amplified signal to the cochlea.
The eustachian tubes connect the middle ear to the nasopharynx. Their main function is to equalize pressure within the ear so that the eardrum can properly transmit sound vibrations to the auditory nerve.
The cochlea is located in the inner ear. The structure of the cochlea is elastic and rolls up, resembling a snail shell. This part of the ear is in charge of converting the vibrations received by the middle ear into nerve signals in order to send them to the brain via the auditory nerve.
To take care of your ears, you should use earphones for no more than an hour per day and keep the volume low.
Today we’re going to learn how the human ear works.
[Music]
Sounds are vibrations that travel through the air in the form of waves. These vibrations reach the auricle and then move through the ear canal.
[Music]
Then the sound waves reach the tympanic membrane, a thin tissue similar to a drumhead that vibrates as sound waves get to it. The three tiny bones—the hammer, the incus, and the stirrup—are connected to the tympanic membrane. Because of the vibrations on the tympanic membrane, the tiny bones start moving and send sound waves to the cochlea.
The cochlea transforms these sound waves into electrical signals and sends them to the brain through the auditory nerve. The brain interprets these signals as sounds that we are able to recognize and understand. For example, we recognize the sound of an ambulance siren and identify it as an alert situation.
