Using a programming language of colored blocks that fit together like puzzle pieces, StarLogo users create games and simulations to study diverse concepts in science and math – such as epidemiology, ecology, geometry, computational thinking, and more. StarLogo is free and runs in an Internet browser, with project sharing options – students can play games created by others, and teachers can use simulations developed by the StarLogo community to illustrate complex concepts. Users can create simple and large-scale simulations using the library of agents or importing their own custom sounds and Collada-format 3D models.
