Engineering is increasingly expected in elementary classrooms now that the "Next Generation Science Standards" have explicitly identified engineering disciplinary core ideas as well as engineering practices. To incorporate engineering into their elementary classrooms, the authors used building blocks (i.e., LEGOS) to help students begin to understand engineered products and how engineers work while engaging them in learning about the structure of matter. By integrating the science content alongside engineering content, the authors hope the students will better understand and apply both sets of ideas. In the lessons described in this article, students are asked to make observations and construct scientifically accurate views that objects are made of smaller pieces and how those small pieces can be used to create a new object (NGSS Lead States 2013). The authors incorporate the K-2 engineering standard that states students will create drawings or make models to illustrate how the shape of an object helps its function (NGSS Lead States 2013). Students learn how to work with constraints when incorporating engineering practices. To further expand on student thinking, both the nature of engineering and the nature of technology are included in the lessons.
