In this lecture, we review how to simulate a the behavior over time of simple negative feedback dynamical system (the filling of water in a toilet tank) using spreadsheet numerical methods. We compare and contrast this with bacterial growth models simulated in similar ways and discuss two basic categories of flow equations that will be used in a variety of different models. We then pivot to discussing how to build stock-and-flow diagrams and implement them in Vensim so that behavior over time trajectories can be generated more quickly.
