This course is designed to satisfy most state requirements for one high school biology transcript credit. Students who complete this course will have a strong foundation for college studies in science and theories about the origin of life. The publisher takes a bold approach by challenging popular theories through use of the scientific method, application of DNA, and recent research to point out strengths and weaknesses of theories. Like all PAC courses, Biology may be completed in a classroom under guidance of a teacher, or through guided independent study with minimum student dependence on the teacher. The design of Biology texts and activities enables students to learn the material with or without oversight by an experienced biology teacher. Lab projects are not required, but may easily be conducted as directed by the teacher.
