The semester courses in the lifepac select series have been compiled using lifepac curriculum. The unique design of the work text format has allowed instructors to mix and match lifepacs from four core subject areas (bible, language arts, history and geography, and science) to create alternative semester courses for junior high and high school students. These courses work particularly well as unit studies, as supplementary electives, or for meeting various school and state requirements. This set includes 5 lifepac workbooks dealing with geology, as well as a teacher's manual. Grades 7-12
