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. The 10 challenges included in this book are as follows: Send a Message (Information Transfer) - Collision Contraption (Energy Transfer) - Solar Heater (Converting Energy) - Wave Models (Waves) - Two Types of Bridges (Bridges) - Testing Telephone Components (Sound Through Solids) - Earthquake-Proof Structures (Engineering Solutions to Natural Hazards) - Save the Pond (Weathering, Erosion, and Deposition) - Big Beaks (Animal Structures) - Sense Games (Organism Structures) Academic vocabulary, time frames, and formative assessments specific to each challenge are provided and most materials needed are found in the classroom or recycling bin. A list of Next Generation Science Standards met by these challenges is provided. This resource is 112 pages in all.
