This project involves creating a simulation of gas atoms in a jar using MicroWorlds EX. Students draw a jar shape and create turtle atoms with random movement rules. When atoms collide with walls or each other, they bounce and slightly increase in speed. The goal is to escape through the open mouth of the jar. Students can experiment with variable like atom number, jar size, and speed increases to observe emergent behaviors. The project provides an introduction to using simulations and models to explore scientific concepts.
