We’re Working on Improving PhET’s Accessibility

Has PhET been slow or simply not working?

We’re actively working on the problem and hope to have it resolved soon. In the interim, if you’re planning on using PhET in your classroom, please consider downloading the simulations in advance to ensure that you and your students can work on PhET sims.

Please e-mail, or post a Facebook or blog message, to let us know when you are having a problem.
