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

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

From babies with big dreams to shaping STEM teaching and learning. Meet a few little folks 👶 who make things happen at PhET! #thisiswho #meettheteam #edusky

24 years of free simulations for classrooms. That’s not changing. What is changing: our license is moving from CC BY to CC BY-NC, to help us ensure commercial users contribute to sustaining the PhET library you love. 🚀 Small update, big mission: bit.ly/small-change...

We’re a #ToolsCompetition finalist in the Accelerating K-12 Learning track! @ToolsCompete is awarding $3+ million this cycle to the next generation of educational tools. Check out all the finalists here. tools-competition.org/26-finalists #PhET #edusky

Experiment with one or two #pendulums, see how the length, weight, gravity, or angle affect the #period. Learners will also observe the system's energy in real-time and discover the conservation of mechanical energy. phet.colorado.edu/en/simulatio... #PeriodicMotion #iTeachPhysics #edusky

"The first step to belonging in math is believing students do belong." Check out our new article in @NCTM MTLT! We share how 6th graders used @PhETsims to explore the mean as a balance point through their own datasets. Read here: pubs.nctm.org/view/journal... #iteachmath #MTBoS #NCTM

"If I teach, I need to be prepared. If I don’t study, what will I teach?" Meet Yrma, a 30+ years educator from Peru who never stops learning! She uses PhET to create a "dynamic classroom" where students have more exploration possibilities Full story: medium.com/@phet-global...

Let your students compare and contrast bar magnets and electromagnets. Discover the characteristics of electromagnets, the variables and the effects each variable has on the magnetic field's strength and direction. phet.colorado.edu/en/simulatio... #iteachphysics #physics #edusky

Build a Nucleus allows students to explore how changes in the number of protons and neutrons affects the nuclear species, the stability of a nucleus, and its possible decay mechanisms. Discover stability and decay trends in the isotopes. #chemistry #chemed phet.colorado.edu/en/simulatio...

PhET Interactive Simulations has just released a new course, Teaching Electricity and Magnetism with PhET Simulations. You will explore PhET’s electricity & magnetism simulations, learn from model lessons, and design your own custom sim-based lesson plans. bit.ly/ElectricityMagnetism #edusky

COMING UP TOMORROW: Learn how simulations can invite student ownership of ideas and allow students to drive investigations through the use of specific questioning strategies, challenge prompts, and metacognitive approach. #teacherPD #PhET Sign up: vz.to/4ht1YnG

Predict how changing variables in a #linearequation will affect the graphed line. With Graphing Lines, students can explore the parameters of the slope-intercept and point-slope form of a #line. phet.colorado.edu/sims/html/gr... #math #iteachphysics #edusky
