PhET provides fun, free, interactive, research-based science and mathematics simulations. We extensively test and evaluate each simulation to ensure educational effectiveness. These tests include student interviews and observation of simulation use in classrooms. The simulations are written in HTML5 (with some legacy simulations in Java or Flash), and can be run online or downloaded to your computer. All simulations are open source.
