The guiding question for this activity is,“How can air be used to move something?” Large air cannons can be made or purchased for students to experiment with while waiting to create ones of their own. An explanation of the science behind the activity is provided. Students will also learn about force, push, and pull. Before beginning this activity, we recommend you read Chapters 9 and 11 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 11 features activities that we believe to be at an intermediate 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.
