This takes some planning and prep but it is fun to do a virtual frog dissection.  It is game-style so of course you want to high score.  When the red question mark appears, you click where it goes.  It's like you are building a frog.  Very fun!  CLick here for the Game but don't forget that there is a whole lesson plan involved right here!
