Expected effects and results
How to use	When voicing a sound, show the red sound tube and let the students feel the vibration of the red cellophane when it against your mouth. When exhaling but not voicing a sound, show the blue sound tube. Put the sound tube to your mouth and let the students feel that the blue cellophane does not vibrate. Also, show the students how to exhale without vibrating the cellophane. For the yellow sound tube, while the students touch their nostrils and feel how they vibrate, place the yellow sound tube to your nose to show them the vibration from the nostrils.
