Today is Global Accessibility Awareness Day. 💙

Recently, we shared our reflection on a decade of work making interactive STEM learning accessible to every student. Today, we want to make it easier for you to use that work in your classroom.

Many of our simulations include accessibility features like:
🎙️ Interactive Descriptions (accessed by screen readers)
🔊 Sonification (sounds that communicate data and change)
⌨️ Keyboard navigation
🔍 Pan and zoom

In the video above, we walk through how to filter our simulation library by accessibility feature, and then demonstrate some features in action with our newest sim Membrane Transport.

PhET Interactive Simulations is calling on parents and students to help co-design new ML simulations. This is a rare chance to work with researchers through a new NSF program—and they require input from families like yours to make it happen.
