Every photograph is used in an instructive manner and is generally overlaid by an illustration, connecting line, or given a side bar with more detailed information. Just enough text to inform and pique curiosity of night sky wonders. Clear explanations and a collection of new words rounds out a glossary in the book's closing. Kids will learn all about the night sky, from the moon to constellations to planets, in this new National Geographic Reader. The level 2 text provides accessible, yet wide-ranging information for beginning readers.
