Objective: The children will explore their sense of hearing and understand how hearing helps us learn about our world.‹ Return to Theme
Note: This lesson requires advance preparation.
Prior to the day of the lesson: For each of the materials (beans, rice, etc.), fill two containers half way. Do not overfill the containers or they will not make much noise. Identify the containers that have the same materials with a symbol or sticker. Glue the lids shut with tacky glue or a hot glue gun and let them dry overnight.
The sense of hearing is one of our five senses: sight, smell, touch, taste, and hearing. Our ears help us hear sounds and take in information about our world and what is going on around us. Our brains use the sounds from both of our ears to determine the direction and distance of sounds. The sounds we hear help us decide whether to enjoy an experience.
The ear consists of three main parts: the outer ear, middle ear, and inner ear. The outer ear collects sounds and delivers the sound waves to the middle ear through the ear drum, which divides the outer ear and the middle ear. The ear drum collects the sound waves, coverts them to vibrations, and sends them to the middle ear.
The middle ear contains the ossicles, three tiny and fragile bones. The bones are known as the hammer, anvil, and stirrup and they are the smallest bones in the body. The eardrum causes the three little bones to vibrate and they carry the vibrations to the inner ear.
The inner ear contains a curled tube filled with liquid. The vibrations from the ossicles cause the liquid to move. The movement of the liquid causes tiny hairs on the tube to move, sending nerve signals to the brain. The brain interprets this information for us as sounds and language.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
