This is the teacher guide, that accompanies REAL Science Odyssey Biology 2 Student Text. It is set up to resemble the student book. Each lesson is reviewed in the teacher's guide with further explanation not found in the student book, as well as answers, suggestions, grading, learning goals, resources, and scheduling. Divided into 32 chapters, both books together provide a rigorous and complete middle school biology course that covers a 36-week school year. Each chapter begins with an entertaining written lesson that is followed by several components intended to reinforce the lesson, address the needs of different learning styles, and engage students in hands-on learning and research. Major topics covered in RSO Biology 2: Cells, Genetics, Anatomy & Physiology, Evolution, Ecology, and Classification
