iCivics

What is iCivics? on Prezi

This is a site that started last year.  The pictures might draw in civics teachers (ie middle schoolers) more than high schools), but it presents some great games to learn about civics.  The main emphasis is on courts (the site is the inspiration of Sandra Day O'Connor).  Above is a Prezi on it.  If you have never checked out a Prezi, that alone is worth looking at (for high or middle school).
