Status Updates From Plot & Structure: Technique...

Chapter 7 - Scenes - Scenes can be 'action' scenes as the lead tries to pursue his goals and faces opposition; 'reaction' scenes as the lead emotionally considers what happened in the last action scene; 'setup' scenes, or beats, that help prepare the reader for the next action scene; and the 'deepening' scenes which add a little spice to the reader's understanding of character or setting.

Chapter 6 - Endings - "A weak ending can ruin an otherwise wonderful book. A strong ending can redeem an otherwise mediocre book." Either the lead reaches his objective, or doesn't, or we are left wondering. You can end with a little poetic line, with some appropriate dialogue, with a description, or just a summary statement.

Chapter 5 - Middles - Here is where you pile on the opposition and stretch the tension, raising the stakes as you go, following the ARM rhythm: Action, Reaction, More action.
