The purpose of this investigation is to examine how teacher candidates create and teach lesson plans that include trade books and the 5E model of inquiry science. Specifically, this study examines how elementary school teacher candidates, enrolled in a science methods course, intended to use trade books to teach interdisciplinary science and English/Language Arts lessons using the 5E Model of Instruction (Bybee, 1997). Inductive qualitative analysis reveals that science trade books can be used to increase the amount of class time spent on science. Implications for elementary pre-service teacher preparation programs are discussed.
