System Feedback
You will be divided into 4 groups. Each group will be assigned a section from this website
(https://lsintspl3.wgbh.org/en-us/lesson/buac20-int-posfeedbackex/1 ) that explains positive
feedback that happens in the 4 spheres of the earth. Please remember that positive feedback
does not mean that something positive or good is happening. Positive feedback in a system
means to reinforce, speed up or enhance the process that’s already underway.
Your group’s goal for this activity is to identify and explain the positive feedback that is happening
in the section assigned to you. You should also identify what spheres are involved in the process.
Discuss your section with your group and present to the class what you found out.
Below is the grouping and the section assigned:
Group 1 (Water vapor): Lucas, Olivia, Kathryn, Sienna, Poiema
Group 2 (Vegetation and soil erosion): Rebekah M, Ben Marks, Karis Fong, JD
Group 3 (Ice Albedo): Rebecca K, Dominic, Karis, Timothy
Group 4 (Ice sheet height): Adalynn, Chris, Lylah, Caleb
