McGraw-Hill designed the Level Blue integrated science book for eighth grade. The textbook covers heredity, ecology, geology, astronomy, chemistry and physics, and it follows the Level Red and Level Green textbooks for sixth and seventh grade.
The online Student Center for the Level Blue textbook features additional projects designed for older middle school students. Students can walk through a virtual pig or owl pellet dissection, complete Internet-based research projects, write presentations and perform interactive experiments. The Student Center also provides section and chapter quizzes, standardized test practice and links to additional online resources. Many sections feature additional math practice for scientific calculations.
