It depends on whether you are currently enrolled in a college or university already. Normally, the Career Center at any college or university is the best place to head to when looking for internships. They usually post them on their websites and can help you put together a resume and begin the search. Since you asked about scholarships as well you might not be in school. In any case, whether you are in high school still or not, you can head over to your high school's guidance counselor's office who can help with both scholarships and internships. You could do a blind Google search for these things but its better to talk to knowledgeable people directly so you do not waste time.
