PhET is a platform for free, fun, innovative, and research-based simulations of physical phenomena. Graphics and intuitive controls help students visually comprehend concepts that are invisible to the eye. The simulations also feature measurement instruments such as rulers, stop-watches, and thermometers that users can manipulate to learn cause-and-effect relationships.
