In this unit, we are going to work with a few fundamental assumptions about gases. The first of them is: gases are made up of many individual particles (molecules).

However, we cannot see the gas molecules inside the air duster can; they are too small to see with only our eyes 👀. Instead, we will use  NetLogo 🔗 to develop a computational model to visualize the molecules inside the air duster can as the air is being pumped into it. NetLogo is a free programmable environment for building and running computational scientific models that simulate natural and social phenomena.

Scientific models 🔗 are used to explain and predict the behavior of real objects or systems and are used in a variety of scientific disciplines. They can be expressed in many different ways. For example, your written explanations and sketches can be considered as informal models of the gas behavior in the air duster can.

Below is a simple particle sandbox modeling toolkit. We can use this simple modeling toolkit to construct static systems that include basic particles and barriers. The short video above demonstrates how to use this tool.

Now let's re-create an approximation of our sketched models of the air duster can using the simple modeling toolkit below! 

Please do not spend more than 6 minutes on this task.
