As mentioned above, the first step to becoming a teacher is to figure out what type of Bachelor's degree you will obtain. The path to becoming a health science teacher is not linear, therefore you do not necessarily have to major in education at the undergraduate level to become a certified teacher in the future. However, you will have to take certification exams, and depending on the state you live in, you may need to complete a Master's degree in education. In addition, the types of courses you will take will encompass a wide variety of subjects such as anatomy, nutrition, disease, stress management, and more. These courses will help you narrow down your interests and pick a major for your degree, whether it is health science, education, or both depending on your school.
All the best.

The first stage to becoming any kind of teacher is to research education degrees you would want to pursue. Start by researching and applying to colleges/universities that have undergraduate education programs. Once you are enrolled in one of these programs, your school will give you all the tools you need to pursue the subject and age group you would like to teach. They will also inform you about how to get state certified to teach in a school, and advise you through this process.
You don't always have to get an undergraduate degree in education to become a teacher. You can pursue graduate programs that help you get certified as well. For example, I graduated with a bachelor's degree in economics. I then entered a fellowship program where I taught at a charter school that paid for me to work and also complete a 2 year masters in teaching. After two years, I had experience in the classroom and also had my certification/masters.
I am not sure how old you are, but if you are in high school, I would start by researching undergrad programs in education. If you are in college, think about alternative paths such as masters programs/ fellowships etc. that could help you become a health science teacher.
