There is always a force between the Earth and other masses. This force is called gravity or gravitation. Gravity affects all objects on Earth. It doesn’t matter if they are on the ground or in the air. In this chapter, the experiments focus on how gravity affects moving objects, how an airplane must fight gravity to stay in the air, and the importance of balance and finding the balance point. Teacher background information, assessment, safety notes, references, and additional resources are provided. This book selection also includes the Table of Contents, Preface, Acknowledgments, About the Authors, An Introduction to Phenomenon-based Learning, Appendix, Image Credits, and Index..
