The GasLab project was designed to help students visualize and explore the physical behavior of an ideal gas and relate the idealized microscopic molecular rules to the measurable observable quantities that emerge. This set of models simulates the behavior of gas molecules in a closed container under various conditions. It was one of the original Connected Mathematics StarLogoT models (under the name GPCEE) and is now ported to StarLogoT as part of the Connected Mathematics "Making Sense of Complex Phenomena" Modeling Project.  
The GasLab models are examples of "extensible models". They are basic seed models that allow students to "peek under the hood" of the model and see how it works. Interested students can then modify the underlying model, creating an experiment or a new variant of the GasLab model.  
The GasLab models are all variations of the basic model called GasinaBox. All variations use the same basic Newtonian (billiard ball) rules for what happens when gas molecules collide. Each model has different features in order to show different aspects of the behavior of gases. Many other extensions of the core GasinaBox model have been explored by students.
