Remote controlled sounds

What is sound? when they hit something, why can I hear it from far away? Could we listen without air? We perceive the sound of the world around us thanks to the medium that allows it to propagate, the air, even if we don't realize it's there; in addition to helping us breathe, allows us to hear. In this activity we will explore how sound propagates through space and through different media., through experiments-gadgets to transmit and observe vibrations.
