Principles of Life (POL) is the first book published to address the College Board’s AP* Biology redesign. Principles of Life emphasizes AP* Biology's four big ideas, helping students build enduring understanding around the essential knowledge skills. The Principles of Life program provides students with opportunities to apply concepts through data analysis and active learning, all in significantly fewer pages than other texts and at a much lower cost. With Principles of Life, you'll find: chapters organized around concepts, pedagogy to support these concepts, a focus on computational skills and data analysis, a textbook students will read, and invaluable supplements written by leaders in AP* Biology. Principles of Life addresses the changes needed to meet the new course demands with an unsurpassed ancillary program.
