PBS LearningMedia has designed this detailed lesson plan to help students understand the role of vibrations in interpreting and experiencing sound. Assembled with elementary school students in mind, the lesson, which has been viewed nearly two hundred thousand times, begins with a clear Overview. From there, it outlines the Objectives of the lesson, suggests the appropriate time needed to complete the lesson (approximately three class periods), and then offers readers links to nine different Multimedia Resources. While the lesson requires specific materials, such as plastic drinking straws, scissors, and large balloons, most of them are easily acquirable and inexpensive.
