A powerfully written, impeccably reviewed textbook serves as the centerpiece of the new McDougal Littell Biology program. Through graphic photos and illustrations, memorable connections that each student can see and feel, and lab activities in every chapter of the book, McDougal Littell brings Biology into the world of a student. The Pupil Edition provides students with a structured framework of key concepts and main ideas upon which to build their knowledge of biology. Critical thinking and problem solving activities tap into the creative energy of a student's mind and help to teach students how to think in a scientific way.
