Gr 3-7-Which is more dangerous-a shark or a spider? What is the tallest building on Earth? Answers to these pressing questions make up the bulk of this compilation of the biggest, fastest, and coolest stuff. Take National Geographic's outstanding presentation and research, add to it the unbelievable records of Ripley's, and you have this exciting volume that's chock-full of cute images (the world's tiniest animals), quirky trivia (Did you know Marie Curie's papers are still radioactive?), and tons of close-up pictures. Guessing games and questions will hold kids' attention. VERDICT A great addition to most collections. This will be well used, so order a few.-Sharon Verbeten, Brown County Library, Green Bay, WI © Copyright 2018. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc.
