This video will provide more information about how System Dynamics (SD) can be helpful in analyzing dynamic systems problems. It describes the characteristics of complex systems and identifies some complex systems that are in the news. It describes the modeling icons used to build SD models and explains a few very basic model diagrams. Two core principles of System Dynamics modeling are highlighted. One secondary student original model is presented. Finally some resources are provided for those who are interested in learning more about the SD analytical approach used to better understand how the dynamic world works.
