Recent reform movements in science education call for integration of multiple STEM (Science, Technology, Engineering, and Mathematics) disciplines with a new focus on engineering education. The Next Generation Science Standards (NGSS Lead States, 2013) highlight the overlap between engineering and science practices and specify learning progressions starting with kindergarten. Previously, engineering education mainly took place at the college level and began upon completion of a solid base of science and math prerequisites (Cunningham & Carlsen, 2014). There is limited research on engineering education at the elementary level specifying what opportunities and challenges this move towards curriculum integration presents.
