This document is a lesson about sound. It defines sound as a type of energy created by vibration. It explains that sounds are made when something vibrates and moves back and forth, causing the air and other materials to vibrate. This vibration travels to the ear allowing us to hear sounds. The document discusses how the pitch of a sound depends on the speed of vibration, with higher pitches associated with faster vibrations. It also notes that sound can travel through gases, liquids, and solids like air, water, and wood.
