Teaching Internship for non-education major (high school junior)

Would join the teaching fellowship in breakthrough silicon valley help with my college applications? I really enjoy teaching but not planning to become a teacher- would it still play a role in apps (I know I will enjoy it but I’m afraid colleges will expect me to do something related to my major over the summer)?

Do it because you think you would enjoy it. No one expects you to do things related to your possible college major just yet.
