The Virtual Laboratory consists of open-source simulation programs illustrating complex systems ideas, theories, and tools, accompanied by curricula designed for both teachers and independent learners.

The Virtual Laboratory is organized into topics, each of which contains a laboratory guide (in PDF format) and a series of simulation models written in the Netlogo language. These require the free Netlogo platform, which can be downloaded from http://ccl.northwestern.edu/netlogo/
