Discover Rocks 
C. Petersen
Discover Rocks introduces your readers to what rocks are and how they form. Real-world examples bring to life igneous, sedimentary, and metamorphic rock. Great images draws in your readers while the easy-to-read text breaks down complex concepts. A diagram of the rock cycle ties everything together and a geology-themed project provides the opportunity for hands-on experience. Gr. 3-7
