## WHAT IS IT?
This is a model of exponential growth using the System Dynamics Modeler.
## HOW IT WORKS
At each step, the value of INFLOW is added to STOCK. The value of INFLOW is always the previous value of STOCK times a specified growth rate.
## HOW TO USE IT
Press the SETUP button, then press the GO button to run the model.
## THINGS TO NOTICE
View the STOCK monitor to see the current value of STOCK.
View the plot to observe the growth of STOCK over time.
## THINGS TO TRY
Use the System Dynamics Modeler to add an outflow.
Try different growth-rate values.
## EXTENDING THE MODEL
Create a new stock that grows linearly. Try having the level of one stock influence the growth rate of the other.
## NETLOGO FEATURES
This model uses the System Dynamics Modeler.
