The document discusses a prey-predator simulation model created using STELLA software. It includes graphs showing the populations of mice (prey) and owls (predator) over time under different starting conditions. The simulation allows testing the impact of changes to the system, provides a risk-free way to study dynamic relationships, and helps visualize complex interactions. Some advantages are that it offers an interactive way to explore problems and build higher-order thinking without building physical models, while disadvantages include needing training to use the software and potentially incorporating errors.
