Every student, at some point in their schooling (hopefully, at many points through their schooling!) will have questions that they want to find the answer to. These might be big questions that their teacher can't answer: What was before the Big Bang? What happens at the edge of the universe? Why are you crying, Sir? Or they might just be small questions to do with how to complete a bit of homework.
I enjoy frequenting http://www.physicsforums.com/ because it's full of intelligent people asking and answering every type of science question you can think of. They'll even help you with your homework! (notice the word 'help', not 'do it for you').
No matter where you are on your educational journey, you'll find something on that forum interesting or helpful, and hopefully both!
