Topic: The
sound.
Sound is a type of energy made by vibrations.
When any object vibrates, it causes movement in the air particles. These
particles bump into the particles close to them, which makes them vibrate too
causing them to bump into more air particles. This movement, called sound
waves, keeps going until they run out of energy. If your ear is within range of
the vibrations, you hear the sound.
