Objective: The children will explore what creates sounds and will develop an understanding of how the speed of vibrations affects sound.‹ Return to Theme
Wooden paint sticks – 1 per child
The sense of hearing is one of our five senses. We use our ears to hear sounds. Sound is made if something vibrates. When something moves back and forth rapidly, the air moves and makes waves. These movements are called sound waves or vibrations. For instance, when you speak, your vocal cords vibrate. The vibrations cause the air to move. The movement of the air creates sound waves that go through the air. The waves enter our ear, the brain starts to work, and we hear the sound waves.
Sounds are affected by how fast or slow the vibrations are moving. Vibrations that move fast create sounds with a higher pitch. Slower vibrations create sounds with a lower pitch. When we extended the stick farther from the edge of the table, the vibrations moved more slowly, and the air created sound waves that moved more slowly, resulting in sound with a lower pitch.
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.
