Apologia fully supports homeschool parents setting their course schedule loads. It is a recommendation, not a requirement, that health be taught at the same time as biology. Exploring Creation with Health and Nutrition, 2nd edition, is not a lab science. If you choose to do it at a different time, please be aware that this is a course which can fulfill the health course requirements that some states have for high school graduation. It does not fulfill a lab science requirement.
