Junkyard Ear

This week in science, we are doing a project on the human ear. The goal of this project is to make a model of an ear and see if all the parts will send vibrations through the whole ear when a loud sound is produced. I think my group will do very well on this project together. Sydney, Haiden, Abi and I have already come up with a plan in order for this experiment to work. So far, we will use a small dog cone for the pinna, which is the outside of the ear that funnels the sound into the ear canal. Then, we will use paper for the ear canal, and ceran wrap for the ear drum so that it will vibrate easily. Then, we will use toothpicks for the malleus and the stapes. The incus will be represented by the bottom of a small paper cup. These 3 bones are the smallest in your body, and we really needed them to vibrate well. We will use a balloon for the cochlea. Inside we will put dog and bunny fur to represent the hair inside the cochlea that plays a very important part in sound traveling through the ear. A straw will be inside the balloon to represent the auditory nerve which send the signal to the brain. Finally, we will use a monster straw to act like the Eustachian tube. We are very excited to test our model out. I hope it works!
