This is the exposition because it introduces the Watson's family and the setting in cold Michigan. In the book, it starts in Kenny's point of view and on a cold day. He also introduces his family and describes what they were doing.
This is the rising action because Byron gets in a lot of trouble. For example, he gets in trouble for playing with fire in the house. It also shows how the conflict is building in the story.
It will be ok, Kenny
This is the Climax because the Watson's are taking a trip to Birmingham because Byron was being bad. This is also the turning point in the story.
NO SWIMMING! DANGER!
This shows the falling action because it is when everyone meets grandma Sands, when Kenny goes to a whirlpool without permission, when there is a church bomb and when Kenny sees the Wool pooh. These events start to wrap up the conflict.
This shows the conclusion when the Watson's come back home from Birmingham and when Kenny was crying with Byron. This shows the Conflict is being solved as Byron was trying to comfort Kenny about everything that happend.
