This Acoustics: The Sound Lab lesson plan also includes:
If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels. Whole class, small group, and individual activities vary the method of instruction and keep class engagement high.
