Interactions within systems and between systems carbon cycle, water cycle, atmosphere, Earth’s energy system Feedback Why do we get / give feedback? at its “heart”, feedback is about cause and effect action (process) leads to a response the response leads to another action:
Interactions within systems and between systems carbon cycle, water cycle, atmosphere, Earth’s energy cycle Feedback Loops… where the cause and effect loop back Negative and Positive Feedback Loops these do not mean “bad” and “good”… let’s see his t t a wh ans e m all you are six years old… and you just got a swing set for your birthday… and you beg your Uncle Bobington to go push you on the swing…
Uncle pushes you (A)… you swing … you SQUEAL with delight … so Uncle pushes you harder … you swing higher … you SQUEAL with more delight …. NOOOOOO I’m scared EEWHEEEE !!!! EEEEE !!!! so Uncle pushes you harder … you swing higher … you realize you are really high… and SQUAWK with fear …. so Uncle pushes you less … WHEEEEEE !!!!
low swing Feedback – Positive and Negative… Definition(s) - Uncle pushes you… pulled push influences swing squawk by gravity you swing … with D swing influences squeal fear you SQUEAL with delight … pushed squeal influences push A by Uncle so Uncle pushes you harder … push influences swing you swing higher … swing influences squeal you SQUEAL with more delight …. high squeal influences push swing B so Uncle pushes you harder … push influences swing you swing higher … swing influences squawk you realize you are really high… and SQUAWK with fear …. squawk influences push so Uncle pushes you less … + + squeal with delight + C
Feedback Loops– Positive and Negative… Definition(s) the result (effect) of a process (A) A feedback is ______________________ that in turn influences (effects) the process (A) itself ________________________ the result (the feedback) may be one event, or a series of events ________________________ A effects B, B effects C, C effects D, and so on… until some X effects A when the feedback amplifies the result (effect) of the process (A) positive feedback _______________________ process (A) ________________ A effects B _______________ B effects C _______________ C effects A _______________ negative feedback _______________________ when the feedback dampens the result (effect) of the process (A) ________________ A effects B _______________ B effects D _______________ D influences A _______________
