In this chapter, a paper airplane investigation highlights scientific and engineering practices. The investigation relates to students’ personal experiences and interests and cultivates enthusiasm by allowing students to develop ideas about forces, motion, and interactions supporting Next Generation Science Standards. In many ways, the investigation promotes long-term understanding of science because students actively engage in generating research questions, data collection techniques, and constructing claims based on evidence and data. Through the combination of hands-on, minds-on experiences provided by the paper airplane exploration, students learn essential scientific practices necessary when conducting investigations. A materials list, teacher background information, assessments, and outcomes are provided. This book selection includes the Table of Contents, Introduction, References, and Index.
