Instructor will hand out straws and scissors and instruct students to cut the straws into 3 different lengths. The students will then blow their breath over the opening and will discover (hopefully) that the length affects sound.

Step 3

Using a dummy microphone, students will learn to project, articulate and enunciate their voices. (This can be part of the lesson or can be done as enrichment activity). Please note that microphones can be researched and microphones can be created through an art project.
