Without high school grades, test scores, and EC information, and information on what your family can/ is willing to pay, it is pretty premature to make a list. Your state flagship might be a great choice. If you can afford it and can get in, Harvey Mudd is a school you may not have heard of yet. There are a lot of schools that can get you to a physics PhD program. For now you should be focused on getting great grades and actively pursuing your EC interests, there isn’t much else you can or should do in ninth grade.
