Each book in the "How Things Work" series features easy-to-read text and detailed color illustrations, many of them cut away to show interior views. Special "Focus On" boxes highlight and explain important scientific principles, and simple "Test It Out!" experiments and activities let readers discover for themselves how things really work.
Great examples of real-life machines with a student activity that connects to each type of machine. Many examples of text structure: captions, sidebars, headings, and subheadings. Vocabulary support throughout. Good informational text for students to browse cover-to-cover or flip directly to a desired machine.
