When watching this video, students will observe that vibrations are created when the handles of the Chinese Spouting Bowl are rubbed, resulting in sound waves that can be observed on the surface of the water in the bowl. An understanding of amplitude and wavelength can be developed based on these observations. The harder the handles of the bowl are rubbed, the louder the resulting sound and the larger the waves, enabling students to observe patterns in cause and effect relationships. Since sound is a form of energy that travels in waves, connections can also be made to 4-PS3-2 (energy transfer.)
