The "Next Generation Science Standards" (NGSS Lead States 2013) have placed a special emphasis on engineering, raising engineering design to the level of scientific inquiry. Therefore, it is important for teachers to integrate engineering processes into their teaching. Students should experience engineering design in their science classes--but the activity itself should not be enough. Students should also reflect on their engineering design experience in light of nature of engineering (NOE) ideas included in the "NGSS." In this article, the authors describe how they integrated reading picture books into an engineering design process and how they used these books to generate explicit and reflective discussions around NOE ideas. This reflective approach intentionally draws students' attention to the relevant ideas described in the "NGSS" while they are engaged in the engineering design process.
