This is from an advance review copy for which I thank the publisher.
Don't tell me you didn't want to know this 'Stuff you should know about'. There are adults who could learn a lot from this, but it's aimed at younger readers, with dazzling, full-page (and multi-page!) illustrations and quite a bit of text. It explains Earth, from the core to the sky, and from dusk until dawn, and from north to south, and from dry to wet - in short, everything that goes on with Earth as a planet is in here: How does the Earth move and orbit, how night and day work, why the moon seems to change over the course of a month, what's under the Earth's crust and how does this make continents move? It covers volcanoes and mountains, rocks and water, air and clouds. It digs into caverns and ocean trenches, and discusses storms, rain and the wind, and offers tips on becoming your own weather forecaster!
Designed from the ground up as a print book, this doesn't work too well as an ebook which is the only version I had access to, and especially not on a smart phone! Even on a decently-sized tablet though, the illustrations need to be stretched to read the text. Some of the pages were single screen, but most were a double-page spread, and some were multipage spreads - I imagine the actual book has some pages where a leaf on one page or both folds out to double the size of the illustration.
I'm by no means a scientist, but I am well-read in the sciences for an amateur and I saw no problems with any of the information here, so I commend it as a worthy and very educational read which will answer pretty much any question a younger child has, and stir up a passion to go find out more detail in older children.
I don't know if the ebook review version, which is the only version an amateur reviewer like myself ever gets access to, was abridged, but mine was in two different downloads. The book is numbered through page 80, where the index begins (there's also a glossary), but the ebook numbering on the bottom of my screen went only to page 21! Now some pages where multi=page spreads, so for example what was listed as page 10 by the ebook reader was numbered on the pages form 20 through 23, but even so, the page numbering went only to 57 on my ebook, so I was missing about a third of the book.
It was also difficult to maneuver in the ebook version - hard to swipe from one page to the next, and troublesome to stretch the pages to read some of the text. Also, it was a bit slow to load the next page. I commend this book as a worthy read (assuming the print book has all the pages!) and based on reading only about two-thirds of it, but I cannot commend the ebook version (assuming that there is one, based on my experience of this review copy.
