Exploring Creation with Health and Nutrition, 2nd edition, has a suggested schedule of three days per week of study for an entire school year. On average, it will take a student an hour of study each of those days. Some projects will require additional time, and students should plan these into their schedules. As with all Apologia courses, we recommend that you tailor the course to fit your homeschool calendar. It could be done in a semester, if desired.
