What is PhET?
Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.

More About PhET's Design
To help students engage in science and mathematics through inquiry, PhET simulations are developed using the following design principles:
- Encourage scientific inquiry
- Provide interactivity
- Make the invisible visible
- Show visual mental models
- Include multiple representations (e.g., object motion, graphs, numbers, etc.)
- Use real-world connections
- Give users implicit guidance (e.g., by limiting controls) in productive exploration
- Create a simulation that can be flexibly used in many educational situations
DescriptionTest the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
Sample Learning Goals
- Determine if a liquid is acidic, basic, or neutral
- Place acids or bases in relative order
- Describe on a molecular scale, with illustrations, how the water equilibrium varies with pH
- Determine concentration of hydroxide, hydronium and water at a given pH
- Relate liquid color to pH
- Predict (qualitatively and quantitatively) how dilution and volume will affect the pH and concentration of hydroxide, hydronium and water
