Support PhET Simulations

If you use our simulations, and/or are interested in supporting science education worldwide, please consider donating to the PhET Project. While the simulations are free, they are expensive to create, test and maintain.

Donations of any size--$10, $50, $100, or more--help make it possible for us to continue to grow our library of simulations, provide on-going support and assist underserved populations around the world. All donations are tax deductible.

For any questions on the donation process, contact Kathy Dessau at [email protected].

NOTE: Donations to PhET are routed through the CU Foundation, the University of Colorado's fundraising partner. CU Foundation is a tax-exempt organization under IRC 501(c)(3) and a public charity under IRC sections 509(a)(1) and 170(b)(1)(A)(iv). All money donated will go directly to PhET.
