Aquatic Notes Objective Students will explore how the mass of water can affect sound vibrations.
Sound vibrations have different frequencies.
Our sense of hearing interprets the changes in frequencies as a change in pitch. A more secure object may vibrate faster than a loose object when struck. As the glass is filled, it becomes more stable and vibrates slower when struck. Action Divide students into groups and assign each group to one shape of cup. Fill cups with water to different levels.
