What’s the difference between Upper Level Experience Astronomy and Experience Astronomy PLUS?

Experience Astronomy (Level B) was designed specifically for middle school students. It includes 35 weekly lectures, quizzes, outdoor observations, and reading assignments. We typically recommend this course for students in 6th-8th grade, however, we have had some students slightly younger than this complete this course.

Experience Astronomy PLUS (Level C) was designed for high school students looking to earn a science credit. This course builds on our Level B program—with all the same lectures, quizzes, and outdoor sky observations—and then takes students to the next level with 12 extra lessons that students receive throughout the year with projects or research papers to accompany each one. We typically recommend students in 9th grade and above take this course, however, some motivated middle school students have successfully completed this course.
