Why Our Ears Make Wax and How It Protects Us

SciShow Kids

This engaging episode of SciShow Kids explores the science behind earwax, scientifically known as cerumen. Host Jessi and her robot rat friend Squeaks explain what earwax is, where it comes from, and the vital role it plays in keeping our ears healthy. Through colorful animations and clear explanations, the video demystifies a bodily function that children often find "gross" but intriguing. The video breaks down the anatomy of the ear, specifically the ear canal, and uses accessible metaphors to explain how earwax acts as a self-cleaning mechanism. Key topics include the production of cerumen, how jaw movement helps move wax out of the ear, and the three main jobs of earwax: moisturizing the ear canal, removing dead skin cells, and trapping germs and dust to protect the eardrum. Ideally suited for early elementary science and health curriculums, this resource serves as excellent material for teaching body systems, hygiene, and personal safety. It directly addresses the common childhood habit of putting objects in ears, providing a scientific explanation for why ears are best left alone to clean themselves. Teachers can use this to spark discussions about how different parts of the body have specific protective functions.
