A collection of fun, interactive, research-based simulations for science and math instruction in Grades K-12 and university, developed by PhET Interactive Simulations at University of Colorado Boulder (https://phet.colorado.edu). All simulations are based on the results of education research and tested with students.
Each PhET simulation provides a highly interactive environment which supports student exploration and discovery – making the invisible visible, including models and representations, providing measurement tools, and emphasizing real world connections.
PhET’s simulation design supports a variety of instructional uses (as lecture demos, labs, homeworks, etc.) and may be coupled with ac
