Internships for High School Juniors/Entering Seniors?

<p>I'm looking forward to interning this summer for something Law, Psychology, or Journalism related in the Los Angeles area, but I have absolutely no idea where to look for these internships. I've been trying to google online especially for law firms, but I believe that most of them are looking for college undergrads. Are there any specific websites or people you know personally that might be able to help? My friend suggested that I contact some USC professors, but I'm confused as to whether or not I need to send a resume? Sorry if I sound completely clueless/stupid, I have no experience with this whatsoever. :P</p>
