The big book of useless science knowledge 250 of the coolest, weirdest, and most unbelievable science facts you won't be taught in school

Gr 3--5--Get ready for any child's favorite phrase: "Did you know…?" That there's a volcano in Indonesia that erupts blue lava? Or that there's a spacecraft graveyard in the Pacific Ocean? Or that some bacteria eat plastic waste? These and other not-at-all useless facts fill the pages of this brightly colored and often silly early elementary nonfiction transplant from the United Kingdom. The chapters cover many topics from all over the world and throughout time, separated into irreverent categories like "Useless Nature Knowledge" or "Useless Earth Knowledge." Almost every spread gives two or three facts with corresponding illustrations, with the "Useless Technology Knowledge" chapter adding the element of pixilation to its pages to amp up the fun. Humorous quips from people, animals, insects, and even aliens keep the tone light and enjoyable. The black font used throughout is hard to read on pages with darker backgrounds, and some vocabulary may be difficult for younger readers. However, there is back matter featuring a glossary of scientific terms and an index. VERDICT A fun and engaging reference point for elementary readers interested in science. A good addition to a grade school library.--Jessica Durham

Organized into topic areas (e.g., "Human Body," "Chemistry"), this collection contains fascinating and occasionally gross trivia about ourselves, our planet, and our universe. Readers learn, for example, that jellyfish can live forever; that you're awake during brain surgery; and that astronauts left poop on the moon. Humorous cartoon illustrations, such as a drawing of lighter-than-water Saturn enjoying a bubble bath, accompany each fact. (c) Copyright 2025.
