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 Gas-in-a-Box. 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 Gas-in-a-Box model have been explored by students.

GasLab Curriculum

A series of Investigations to guide the use of GasLab in the classroom is under development. This is an interactive, hands-on curriculum that will enable teachers and students in middle school and high school to work easily with GasLab models in a variety of school settings - as a class or in small groups. It can be used either to structure demonstrations and discussion, or as student worksheets, or to guide students in extending the models as independent projects.

Write to us ( feedback ) for the password and with any comments or suggestions you have!
