All the Water on Earth

K-Gr 5–Readers are guided along a gentle but thorough stroll through all things water, from the water cycle and phases of water in the environment to how humans use (and misuse) our resources. The text covers a lot of ground, skating quickly through many concepts rather than delving very deep—this is a big-picture, big concept book more than for research—but it leaves readers with a sense of how massively important water is to life on earth. The closing line hits hard: “all the water on Earth/ is all the water on Earth.” Goodnight’s mixed media illustrations are a vibrant and engaging match for the text. A mix of full-bleed and ­spotlight ­illustrations features a diverse cast of ­children interacting with water in many ways, creating a strong connection between older and younger ­children and supporting the broad scope. Back matter includes discussion ­questions, further ­reading, resources, and an author’s note encouraging readers to take steps to protect water resources.
