Here are some games you can play that will help you practice Chemistry over break.  You will probably have to play each game several times, until you get all the answers right.  Make sure you focus on learning Chemistry (not finishing the game...)

For some of these games you will need your periodic table.  But, if you don't need it, try not to use it!!

(Note:  you will not know some of these answers.  Just do your best!)
