At #LitMath26 in Charlotte this week: Catherine Carter on using free interactive sims to energize math class. Wed Aug 5, 10:00 to 11:15 AM, Room W207A. Bring a device and try them with us.

New from PhET: a professional learning library, all in one place. 200+ resources for growing your practice with sims, and you can filter by subject, grade level, and length: how-to guides, webinars, and full courses. https://f.mtr.cool/tkfarncvvl

World Cup season is a fun way into the trickiest idea in stats: the mean. In Center and Variability, students become the striker. Every kick is a data point, and the mean and median move in real time. https://f.mtr.cool/umhpfnpqex

While students are away, the PhET team is at play!⚛️ We're using every minute of summer break to bring you something we've been building toward for a long time. Learn more about our Quantum Education Initiative 🔗 https://f.mtr.cool/nnveocedmh #PhETSimulations  #QuantumEducation

Today is Global Accessibility Awareness Day. 💙 Many of our sims include features designed so every student can experience the same depth of interactive STEM learning. In this video find out how to find the sims with the features your students need. https://f.mtr.cool/xgzabtblro

What does it take to make #PhET's interactive sims accessible? There's no text alternative that replicates the experience of discovering Ohm's Law by building a circuit. Learn more about our accessibility work:

PhET’s 10-day #springfundraiser Support efforts to bring 5 popular legacy sims to HTML for the next school year. As a small nonprofit, PhET relies on support from our community to keep creating high-quality, open educational resources for science and math giveto.colorado.edu/campaigns/50...

We just got back from #NSTA2026 in Anaheim and we're still smiling. Teachers loved talking about our upcoming Quantum sims, the new sim Membrane Transport, and were curious about PhET Studio. Thank you to every educator who said hello. You're why we do this. 💙 #PhET #ScienceEducation #STEMed

Parents & educators! Help @PhETsims design new Machine Learning sims. This NSF project REQUIRES co-creation between researchers and families. 1️⃣ Use the link to submit ideas. 2️⃣ Mention "PhET simulations" in your entry. 3️⃣ Submit by Monday, April 20. Visit: airtable.com/appIWEuYz46j...

Happy #WorldQuantumDay! Today, we celebrate the incredible potential of quantum science. The quantum workforce needs better education tools, as existing tools haven't kept pace. We are building them and invite you to join our community. bit.ly/PhETQuantumSurvey2026 #QuantumWorkforce
