Gr 3–5—Each book in this series focuses on a specific area of tech, with two-page spreads on items ranging from batteries to MRI machines and planetary rovers. Each spread explains the basics of the technology and features a notable inventor, allowing readers to learn about key pioneers. The information is delivered through text boxes, speech bubbles, and short paragraphs, and despite the concise format, there’s a surprising amount of introductory content. These books are ideal for students seeking reference on less-discussed technologies or a quick introduction to complex inventions. Plenty of colorful photos and illustrations accentuate the text and make the books visually appealing. Each book concludes with review questions, a glossary, an index, and further reading suggestions. VERDICT Not a must-purchase, but a solid addition for libraries expanding their technology sections.
