Computer Simulation
Computer Simulation is a way to test ideas by running them on a computer instead of trying them in real life.
Before baking a cake, you can write out each step on paper. You check the steps to catch mistakes early. A computer simulation does the same thing, but faster. It runs your plan as a program so you can find problems before using real materials.
Explaining computer simulation by grade level
You can use a computer to try things out before you do them for real. Think about a game where you roll a ball on a screen. The computer shows where the ball goes. You learn what works without having to set it all up.
Projects that explore computer simulation
Testing a mathematical idea about billiard ball paths on a real table would take months — you'd need to set up thousands of physical configurations, one by one. Instead, you write a program in the Logo programming language to simulate a ball bouncing inside a rectangular table. The simulation runs 63 different launch angles, each paired with 100 different table sizes, producing 6,300 complete paths in the time it would take to rack up a single real game.
Personality profiles shape how a Monopoly player behaves, but whether aggression or caution wins depends on who else is at the table. To find out, you program two AI players — Type A plays aggressively, Type B plays cautiously — alongside a Random player that serves as a control. The computer plays 300 games across three sets of 100, each set using a different mix of these players. In three-player games, Type B wins the most while Type A wins only about half as often, but in two-player games the gap nearly disappears.
