Model
The first model will throughly show the different steps of binary fission. There is a world with one randomly-placed stationary particle. There will be two buttons, reset and step. Each time the reset button is clicked, the cell will return to its original position and phase. Each time the step button is clicked, the cell will move to its next phase in binary fission and show it visually. The step button can only be clicked four times because there are only four steps in binary fission. After the fourth time, the step button will be disabled.
Simulation
There is a world with multiple randomly-placed, stationary particles. There will be a reset and play button. The reset button will place the particles in random spots in the world. The play button will cause the particle to repeat itself and divide it. Once the play button is clicked, the button cannot be clicked again until the reset button is hit.
