This is just a visual aid to help them see what is happening to the “eardrum” (plastic wrap) when exposed to loud noises.
Give each young person or small group about 10 grains of rice or salt. a rubber band, if using rubber bands to hold the plastic wrap in place.a piece of plastic wrap large enough to stretch over the lid of the cup and stay there securely.Give each young person or small group the following supplies:.Inner ear: The part can also become infected and would need treatment by your doctor. You should never stick anything in your ear canal because the eardrum can be punctured or torn. If this happens, your doctor can prescribe a medicine (such as an antibiotic) to help treat the problem. Middle ear: This part can become infected. If you have pierced ears, be sure to keep them clean with a sterile solution or they can become infected. It should only be cleaned out if your doctor says it’s OK. Even though earwax can seem kind of icky, it is normal and usually healthy. Whatever you do, don’t stick anything larger than your elbow into your ear. Sometimes shampoo or soap can get stuck behind them so rinse well! Outer ear: This is the only part you should clean.You can wash behind your ears and around the outside. The nerve signals send the messages to your brain that become the sounds you hear. Inner ear: This is where the vibrations from the middle ear create nerve signals. The space in the middle ear is filled with air.
Middle ear: Vibrations from the eardrum travel through the little bones of the middle ear (ossicles) and are sent to the inner ear. The middle ear is separated from the outer ear by the eardrum. The outer ear is where sounds are collected and moved along the ear canal toward the middle ear. Introductionĭescribe the three basic parts of the ear, using the Your Ears Handout as a visual guide (see What You Need). The youth will play a listening game to learn more about their hearing and how important it is to keep their ears healthy. This lesson will introduce young people to the structure of their ears and how they work through a diagram and by building a model ear drum.
