Introduction
Can you hear me? Well I think so. Well today we will be taking a interesting journey, where you will learn a lot more about the ears. Little ears, big ears we still use them the same. Do you want to learn about the functions? Do you want to know about the different part of the ear? Sound waves there and sound wave here, treat your ears with much care. On a learning adventure we will go today, Come along students!!
Task
In this web quest , you will gain information about the ear. With this information you will know the importance of your ears. Hence reading information given and also watching the videos will then widen your knowledge about your ears.
The task includes;
- Write down all the main parts of the ear.
- write the function of all the parts that was written.
- Identify the parts of the ear when seen.
Process
The Outer Ear: Collecting Sounds
The outer ear is made up of the pinna — also called the auricle — and the ear canal. The pinna is the part of the ear you see on the side of your head. It's made of tough cartilage covered by skin. Its main job is to gather sounds and funnel them to the ear canal, which is the pathway that leads to the middle ear. Glands in the skin lining the ear canal make earwax, which protects the canal by cleaning out dirt and helping to prevent infections.
The Middle Ear: Good Vibrations
The middle ear is an air-filled cavity that turns sound waves into vibrations and delivers them to the inner ear. The middle ear is separated from the outer ear by the eardrum, a thin piece of tissue stretched tight across the ear canal. Sounds hit the eardrum, making it move.
The Inner Ear: Nerve Signals Start Here
The vibrations from the middle ear change into nerve signals in the inner ear. The inner ear includes the cochlea and the semicircular canals. The snail-shaped cochlea changes the vibrations from the middle ear into nerve signals. These signals travel to the brain along the cochlear nerve, also known as the auditory nerve.
With the information above and the aid of the video:
- Students should open the you tube link place below in order to gain information about the ear.
- Students should create their own notes on the function of the ear and also the parts of the ear by watching the video given and reading the information provided.
- Student will then draw and label a model of the ear.

Conclusion
This video will be helpful as it will help to foster those auditory learners as well as the visual learners. In conclusion i can be seen that the ears are important to us. The human ear, like that of other mammals, contains sense organs that serve two quite different functions: that of hearing and that of balance and coordination of head and eye movements. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear.
