Dynamics of Scrooge’s Generosity in A Christmas Carol
Overview: Students will gain an understanding of threshold (or “tipping point”) behavior by examining the cumulative influence of the ghosts on Scrooge and the resulting changes in his behavior.
Students will identify key characters and variables within Charles Dickens’ A Christmas Carol.
Students will create behavior-over-time graphs (BOTGs) of the following, or similar,variables: Cumulative Influence of Ghosts and Scrooge’s Generosity
Students will create a stock/flow (S/F) Map depicting the relationships among the following, or similar, Influence of Ghosts, ‘Generosity, and Scrooge’s Threshold/Tipping Point.
Students will demonstrate understanding of thresholds /tipping points through experimentation with a system dynamics model similar to their S/F map and through written explanations of thresholds found in various systems in life.
This lesson was developed for 7th grade Language Arts, but it may be adapted to other classes.
