I found this book to be well written and easy to follow, perfect for a 6th grader to understand. I found the constellation quizzes and maps were perfect to photocopy and give to the students to practice recognizing common constellations. The book also sites some good activities to do with your students as well as how to make different astronomical gadgets, such as a solar stone. I would really like to see an updated version of this book. It was published in 1977 and mentions that in the 80's we will learn more about the outer planets!
