What college courses would I need to take to be able to teach physical education?

It will depend on where you want to go to school. Many universities will have degree programs specifically for teaching physical education... for k-12. Some people choose to obtain a regular elementary or secondary education degree and then do additional courses in physical education that will allow them to teach that subject area as well as general ed or another specific subject.

This is a question you would be better of asking your adviser when you get into your school. Most universities will assign you to a faculty member who will help you register for classes each semester. As an incoming freshman, if you are not sure of your major you are better off not declaring one and staying with the general curriculum that all students have to take (English, Math, Sciences, History, etc).

Don't worry about it too much ;) Your advisers are there to help you.
