The course is contained in two books (student text and teacher guide). The student text starts each chapter 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. These components include lab sheets, lab reports, problem sets, activities, famous science research assignments, poetry, quizzes, and tests. The teacher guide provides all the help a science novice needs to assist her student including suggested course scheduling, summaries, additional material and explanations, sample reports, learning objectives, answers and suggestions, and test answer keys. Divided into 12 chapters, Astronomy 2 provides a complete semester-long astronomy course that is generally completed in 12 to 16 weeks. Some lab work, such as monitoring the sun and the moon over an extended period of time, is continued after completion of the main course.
