Strong pedagogical features to aid comprehension include: Case Studies, boxed articles such as Fun Facts and Points of Interest, Your Turn activities, suggestions for Off-Road Exploration, connections to STEM concepts, Career Profiles, Design Briefs, and example pages from Engineers' Notebooks. Each chapter concludes with questions designed to test the reader's knowledge of information presented in the chapter, along with a hands-on challenge or exercise that compliments the content and lends itself to exploration. Key vocabulary terms are highlighted throughout the book and emphasized in margin definitions.
