Empowering students to utilize science and mathematics to solve the world's problems is needed to prepare them for their future. To do that, science and mathematics teachers must know how to integrate engineering into their classrooms. In this chapter, we describe a novel museum-based field experience for novice science and mathematics teachers to develop their pedagogical content knowledge for teaching engineering and disciplinary practices. This field experience used the Design Lab exhibit at the New York Hall of Science as a way to introduce these novices to design-based and student-centered learning. Through the iterations of this experience, we found it critical to scaffold novice teachers' understanding of how to use disciplinary practices and engineering ideas to help students learn. What worked and future directions will be discussed. [For the complete volume, "Pedagogical Content Knowledge in STEM: Research to Practice. Advances in STEM Education," see ED613708.]
