RSO Astronomy (level 2), written by Blair Lee M.S., is a comprehensive astronomy course at the middle school- to high school-level (grades 6 through 10). But unlike many science textbooks, RSO Astronomy 2 is not a dry collection of facts and worksheets but rather an in-depth course that engages young people’s minds at the same time that they are actively participating in the learning of astronomy. The course is contained in two books (student text and teacher guide). 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.
