Rock-ology: The Hard Facts About Rocks

Bringing rocks down to a microscopic view, this book shows what rocks are composed of and how they fit our world.

There are thousands of different types of rocks, but they have more in common than one might think. After a table of contents, the first pages dive into a basic look at rocks and what happens when they are taken under a microscope. From various mineral compositions to crystals and gems, the basics of rocks and their variety is introduced in a way young readers will understand. Each page spread, or chapter, has a main theme, which is then explained in a few short sentences. Small pictures with extra tidbits and explanations are added here and there, adding more interesting pieces of information curious readers are sure to enjoy. Each spread also includes a large, real-life picture which shows the mineral, crystal or rock in an actual setting.

After the reader learns what rocks are composed of and the difference between rocks and crystals, there are several more pages at the end, which help deepen this knowledge. A mineral chart gives a quick view at very common minerals; a science lab hints at a way readers can build their own types of rocks; a glossary not only defines several more difficult terms but also has a quick picture for each one; and the address to a website, where readers can discover more about rocks, is given.

This book presents the world of rocks in an easy to understand manner, while keeping the topic from growing too dry. The bits of added information give it a little more charm, and the pictures ensure that the knowledge can be tied into everyday life. Young readers will see rocks in a different light after reading this book, and are sure to investigate stones on their own.

Vibrant, full-page photos combine with accessible, comprehensible text in this fresh exploration of all things rock. While the subject matter could have been dry and uninteresting, it is instead engaging, thanks in part to quick facts, stunning images, and an appealing design. Interactive elements, such as sidebars with open-ended questions and the experiments found in “Science Lab,” allow young readers to gain a better understanding of the topic through hands-on and critical thinking activities. The books contain a pronunciation guide in the glossary but not within the text, which may present challenges to readers. While some repetition is to be expected, especially between the individual volumes dedicated to the three rock types and What is the Rock Cycle?, several points are noticeably repeated throughout the series. In spite of some flaws, these are inspired, attention-grabbing titles.
