Spend an afternoon reviewing the statistics. Discover how the Krebs cycle works. Learn about the fundamentals of musical notation. Or, if you feel particularly adventurous, learn how the fire-stick breeding changed the landscape of Australia. It does not matter if you are a student, a teacher, an educator in the home, a director, an adult who returns to the classroom after 20 years, or a friendly alien who tries to improve in earthly biology.
