Studying Sinkholes

Publisher Marketing: In this book, students see the scientific method at work in a real-world situation. Readers practice close reading as they look for clues that will lead to a deeper understanding of erosion, sinkholes, and Earth's structure. The scientific method pushes students to apply critical thinking as they learn new methods of exploration and build on concepts they may already know. Additional tools, including a glossary and index, help students learn new vocabulary and locate information. Contributor Bio:  Orr, Tamra B Tamra B.
