Subject: black light

My 7th grade science class is studying light. A lot of the kids keep
asking about black light. My understanding and limited research is that
it is UV light - beyond the visible spectrum. Then how come we can see
it? Why do flourescent colors and white glow? What is black light? I
would appreciate some info., thanks, Andrea
