Everything we hear in our day-to-day lives has a distinctive sound, from the jingling of keys to the tapping of footsteps in a hallway. Sound is created when objects vibrate. These vibrations cause the air around them to vibrate, sending sound waves in various directions. Some objects known as their resonant frequency. In this activity, students will explore the vibrating nature of sound and how it travels from molecule to molecule. Students will experiment with how sound waves or vibrations can be observed, and will compare and contrast the tend to vibrate at a specific rate. This is
