The guiding questions for this activity are,“How is sound produced and can you make an instrument that produces sound?” Make sample maracas for the students to try and then provide real maracas of different shapes and sizes for students to play with. The science behind the activity explains in more detail how sound is made from vibration and how a maracas percussion instrument called an idiophone, makes sound by vibrating the entire instrument. 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.
