Outline, Systems Thinking

1. Outline, Systems Thinking http://serc.carleton.edu/integrate/teaching_materials/syst_thinking/index.html Why we should all teach systems thinking Systems thinking and NGSS How to introduce systems thinking with InTeGrate Role of metacognition

2. Traditional thinking

3. Systems thinking Traditional thinking model by Ellie Hadler (Williams-Mystic S17) using http://ncase.me/loopy/

4. Why use systems thinking? To address complex environmental problems, we need to approach them holistically, not just one piece at a time. http://serc.carleton.edu/integrate/teaching_materials/syst_thinking/index.html

5. Systems thinking and the NGSS Crosscutting concepts 4. Systems and system models. Defining the system under study—specifying its boundaries and making explicit a model of that system—provides tools for understanding and testing ideas that are applicable throughout science and engineering. 5. Energy and matter: Flows, cycles, and conservation. Tracking fluxes of energy and matter into, out of, and within systems helps one understand the systems’ possibilities and limitations. 7. Stability and change. For natural and built systems alike, conditions of stability and determinants of rates of change or evolution of a system are critical elements of study. From Appendix G (NGSS, 2013)

9. Poll 1: How do you rate your knowledge of systems diagrams right now? Enter selection on the poll. (If you don’t see the poll, enter your selection in the chat box. ) I've never heard of systems diagrams. I've heard of systems diagrams, but cannot elaborate. I could explain a little about systems diagrams. If given a systems diagram, I could explain it. I could create a systems diagram and then explain it.

11. Here is a simple system: faucet Water in bathtub drain

12. The water in the bathtub is the reservoir faucet We measure the amount in the reservoir • Water level in cm • Liters or Gallons Water in bathtub drain

13. The faucet represents a flux We measure the rate of water flowing through the faucet • cm/second • Liters/second faucet Water in bathtub drain

14. The drain also represents a flux We measure the rate of water flowing through the drain • cm/second • Liters/second faucet Water in bathtub drain

15. Water in hot water heater Which type of feedback loop? Balancing (negative) feedback loops hold a system to an equilibrium state and make it more stable. Reinforcing (positive) feedback loops tend to move a system away from equilibrium and make it more unstable. faucet Water in bathtub purifier drain Basement tank

Reinforcing (positive) feedback loops tend to move a system away from equilibrium and make it more unstable. faucet Water in bathtub purifier Yes or No? “This a reinforcing feedback loop.” drain Basement tank

18. Reinforcing feedback loops underlie many environmental problems What are some examples? Type your answer into the chat box  Recall: Reinforcing feedback loops tend to make a system more unstable.

21. Wildfire Smoke over Minnesota Length of summer Heat in the atmosphere Dry trees, plants in Canada Radiative heating Feel free to type ideas into chat box while we listen http://www.mprnews.org/listen?name=/minnesota/podcasts/climate_cast/2015/07/millerclimatecast_20150709 (0:38 until 2:20 Eric S. Kasischke begins speaking) Does the diagram fully represent the complexity of the system described by the speaker?  If not, what reservoirs and fluxes should be added to the diagram?

22. Wildfire Smoke over Canada Length of summer Heat in the atmosphere Dry trees, plants in Canada Wind Radiative heating Radiative heating Smoke over Minnesota Albedo Dirty/sooty ice Deposition One option

23. Wildfire Smoke over Canada Length of summer Heat in the atmosphere Dry trees, plants Wind + Radiative heating Radiative heating melting + Smoke over Minnesota Albedo Dirty/sooty ice Deposition Identify feedback loops
