i love the look on Jack's face here. all along he's been planning and scheming and ready to go with his master plan and not give a hoot to whatever happens to anyone else. but when Will gets stabbed his face has a look of genuine concern for what will happen to Will and Elizabeth.
Great visual for monitoring weather patterns. You could designate a student to be the class "meteorologist" for classroom jobs. You could also keep a bar graph of the weather to teach data keeping/ interpreting.
