Act 1 begins with the witches in some unknown place where they plan their meeting with Macbeth.  The 2nd scene is near the battlefield in Scotland.  Here we hear about how bravely Macbeth fought and that Duncan is going to name Macbeth the new Thane of Cawdor.  The 3rd scene is on the heath where the witches deliver their prophecies to Macbeth.  The location for scene 4 is not specific, but it appears to be at Duncan's castle.  Scene 5 is at Macbeth's castle where Lady Macbeth gets her husband's letter telling her of the witches' prophecies.  Scenes 6 and 7 are also at Macbeth's castle, Dunsinane.  This act sets the scene for what follows - the murder of Duncan.  We clearly see that appearances will be deceptive - Macbeth and Lady Macbeth welcome Duncan like a guest knowing they plan to kill him.  Act 3, scenes 1 and 2 are at Macbeth's castle.  Scene 3 is somewhere in the Scottish countryside.  Scene 4 is back at Dunsinane.  Scene 5 is the barren heath and the witches again.  It is not clear where the last scene takes place, but it is likely that it is Lennox's home.  I'm not sure I'd pick out one theme for the act, but we see Macbeth becoming desperate - his fears in Banquo's loyalty cause Macbeth to have Banquo killed.  We also see that the witches aren't finished with Macbeth yet.  They plan to make him feel secure.  We know Macbeth feels guilty and that he has enemies.
