Hello everyone I am telling you about SOUND enjoy
Sound is made of vibrations moving through matter such as air.
In our middle ear, we have something called the eardrum. This eardrum picks up the vibrations from the sound. When sound waves hit your eardrum, your eardrum vibrates.
When sound travels through the air, your outer ear catches them. the outer ear directs the sound waves into your ear through the ear canal. As you can see from the above diagram, the ear canal is a narrow pathway compared to the outer ear. The sound waves that are picked up push against your eardrum and make your eardrum vibrate.
As your eardrum vibrates it makes the three tiny bones in the middle ear move. These bones are called the auditory bones. These bones send the vibrations to the shell-shaped part of the inner ear called the cochlea. This area is filled with liquid and lined with thousands of tiny hairs. The sound vibrations make the liquid move, and this makes the hairs wave back and forth. The hairs are joined to nerves that send a signal to your brain. your brain then lets you know what you are hearing. It sounds like a complicated process. Well, this all happens in less than a second.
I did an experiment with a cup and a string.
This is me and my friend using cups to hear each other. Please go check out her blog her blog name is Skycoo_forevers blog, she also has a bunch of stuff and it is amazing.
What we did:
This is what you need to make it 2 cups and 1 string.This is how you make it, cut a tiny hole in each center of the cup get your string put it in the tiny hole tie the string when its in the hole, and that is how to make it.
I hope you enjoyed it goodbye everyone have a great rest of your day.
