Q3: 'The Science of Sound' - Read the passage aloud

Sound is all around us—from birds singing to engines roaring. But what is sound, really? It’s a vibration that travels through air, water, or solid objects. Our ears pick up these vibrations and send signals to the brain. In science class, students learn how pitch and volume work. High-pitched sounds vibrate quickly, while low-pitched ones move slowly. Volume depends on the strength of the vibration. Musicians use this knowledge to tune instruments and create harmony. Engineers use sound waves to design better speakers and even study earthquakes. Understanding sound helps us appreciate music, communicate clearly, and explore the world around us.
