If you're interested in physics, there's a few MIT courses that are on youtube. Dr. Walter Lewin is an amazing professor and every lecture has a demonstration to show you what he's describing. These lectures were an essential companion to my own education during freshman year.
For classical mechanics:
Lec 1 | 8.01 Physics I: Classical Mechanics, Fall 1999
For Electricity and Magnetism:
Lec 1 | MIT 8.02 Electricity and Magnetism, Spring 2002
For Vibrations and Waves (an essential primer if you wish to understand Quantum Mechanics):
Lec 1 | MIT 8.03 Vibrations and Waves, Fall 2004
EDIT: I can just about promise you that this will not be boring. However, my own bias is clear. I think Dr. Lewin presents things in such a way as to bring fascination to the student, and even students who once thought physics was boring come away with a real appreciation of how much fun it can be.
