Spark students' imagination with this resource full of grade-level appropriate challenges and tasks. With the activities in this book, students will work individually and collaboratively to ask, imagine, plan, create, build, test, and improve. Teachers are given the tools to guide students through the steps of the engineering design process and the scientific inquiry process, helping them to build a clearer understanding of science and engineering practices (SEPS), disciplinary core ideas (DCIs), and crosscutting concepts (CCCs). Each challenge is scaffolded from an engaging Introduction to a student-driven Mini Challenge. Each unit culminates in a Main Challenge in which students put what they have learned to the test.
