The guiding question in this activity is,“How is sound produced?” In this activity, students assemble harmonicas to learn about vibration, pitch, and harmony. The science behind the activity explains how sound is created when something vibrates. Before beginning this activity, we recommend you read Chapters 9 and 10 which are in this book selection. Chapter 9 is an overview of the section and introduces the format used to present ideas for Family Science Night activities. Chapter 10 explains that these activities are what they call novice level. A materials list, references, safety notes, standards, and teacher background information are provided. This book selection also includes the Table of Contents, Preface, Acknowledgments, About the Authors, Introduction, and Index.
