Simulations and Making Choices
Simulations are computer programs that pretend to copy a real-life event. They usually let you explore what happens when you make choices.

A variable is something that can change in a simulation.

Are Simulations Helpful?

Simulations let you try things out that could be too dangerous, expensive or impossible to do in real life. If you crash a car in a simulation for example, nobody will be put in any danger and no car will need repairing.

There are problems with simulations though they are often too simple and can be very expensive to run. Sometimes a simulation is used at first but the results are then tested out by using the real system.
