School students care about what is happening in the world.  They know that there is life beyond their own communities and countries, and they know, even if they cannot explain or systematically understand, that there are powerful forces operating in those other parts of the globe that they might know only from television or second-hand anecdote.  What they often do not know is how those forces interact with their own lives and concerns, and what they can do to help make sure those interactions are positive.
