Activities
- Research: Use the computer or tablet to research how the ear works. Take notes on the different parts of the ear and their functions.
- Diagram: Draw a labeled diagram of the ear, including the outer ear, middle ear, and inner ear. Make sure to include the important parts you learned about during your research.

Fourth Grade Talking Points
- "The ear is an important part of our body that helps us hear sounds around us."
- "The ear is made up of three main parts: the outer ear, the middle ear, and the inner ear."
- "The outer ear consists of the visible part called the pinna and the ear canal. The pinna helps collect sound waves, and the ear canal carries those sound waves inside our ear."
- "The middle ear has three tiny bones called the hammer, anvil, and stirrup. These bones help amplify the sound vibrations and transmit them to the inner ear."
- "The inner ear contains the cochlea, which is responsible for converting sound vibrations into electrical signals that can be understood by our brain."
- "The electrical signals from the cochlea travel through the auditory nerve to the brain, where they are interpreted as sound."
- "Our ears are amazing organs that allow us to enjoy music, hear conversations, and be aware of sounds in our environment."
