Sound is what you hear! 👂 It's made when things vibrate, which means they move back and forth really quickly. When something vibrates, it makes the air around it move, and that moving air travels to your ears. Your ears then tell your brain that you're hearing a sound! Different vibrations make different sounds – like a loud bang or a soft whisper. Vibrations can travel through air, water, and even solids!
