No, and that’s the beauty of the Young Explorer Series. We recommend you begin with the topic you and your students believe to be most interesting right now. Download the first lesson of each Young Explorer title to explore them in more depth before choosing. Some parents find that teaching the more complicated Anatomy & Physiology and Chemistry & Physics courses are best reserved for upper elementary students. Apologia offers regular and junior notebooking journals for Young Explorer titles.

We offer a curriculum path chart as one possible course sequence for the Young Explorer Series.
