The engineering, technology, and applications of science disciplinary core ideas (DCIs) address questions about the ways in which engineers use science to develop solutions, the process of design, and the effects of our designed world on nature and, ultimately, on our own fate. This chapter outlines a number of difficulties faced by science teachers trying to integrate teaching engineering design into their science classrooms, and the authors hope it has been a step forward in helping them become more familiar with engineering design. While three of the four sets of DCIs focus on specific disciplines, the fourth concentrates on the tight relationships between science and engineering and their effects on the natural and designed world. A list of materials, teacher background information, assessment, standards, safety, and references are provided. This book selection also includes the Table of Contents, Foreword, Acknowledgments, About the Editors, Contributors, Appendix, Image credits, and Index.
