Children's Literature - Elizabeth Leis-Newman
Igneous rocks earn their name because they are made by fire. Lava, for example, can harden into igneous rocks. Planets Mercury, Venus, and Mars are mostly igneous rocks, and the Moon is entirely igneous rock. In fact, every time a volcano erupts, new igneous rocks are formed. Sections in this colorful book, complete with large pictures, include Igneous Rock Formation, Big-Time Basalt, Great Granite, and Super Silicates. In the latter section, Aloian explains how silica is a type of silicate known for its hardness and abundance, and that computer microprocessors are made with silicon chips, hence the name Silicon Valley. Granite is another example of common igneous rock, and is often used to create granite flooring or countertops. While the glossary and real-life examples provide a beginner's guide to igneous rocks, the concepts of rock formation can be difficult to grasp. Sections called "On the Plates" and "The Earth's Structure" will likely be a bit too big-picture for students. Luckily, Aloian's other sections are informative, and provide activities like "Make Your Own Crystals" that will help geology come alive for students. While it is hard to imagine a middle reader kicking back with this book for fun, it is educational and well-researched. It has language appropriate for an upper elementary school student and would be a good choice to complement a unit on rocks. It is part of the "Let's Rock" series from Crabtree.
