@GoogleQuantumAI Happy #WorldQuantumDay 2026! Our Quantum Measurement sim lets you visualize what's happening at the quantum level. Adjust parameters and observe outcomes to build your own intuition for superposition and probability. phet.colorado.edu/en/simulations… #PhETsims #GoogleDoodle

Happy World Quantum Day! Today’s #GoogleDoodle represents the potential of the qubit. We’re harnessing its unique quantum properties to build systems capable of solving problems that remain intractable for classical computers → goo.gle/4ckighH

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/PhETQuantumSur… #QuantumWorkforce

Heading to NSTA Anaheim? Be among the first to try the new PhET + Tuva workflow. Students experiment in PhET and instantly see data in Tuva, with no spreadsheets or manual entry. Thursday, April 16, 3:40 pm PDT | Anaheim Convention Center Room 202B. docs.google.com/forms/d/e/1FAI…

500+ rural students in Puno, Peru went from passive memorization to real experimentation, with zero internet. See how PhET Instructor Edward is transforming learning in the Andean region. @phet-global/pedagogical-leadership-stem-and-phet-in-andean-rural-education-f1e5dd77bf75" target="_blank" rel="nofollow noopener">medium.com/@phet-global/p… #PhETStories #iteachmath #math

@clw9999 @clw9999 It’s wonderful to hear your students are staying engaged and challenged. Keep up the amazing work!

@PhETsims I absolutely love your stuff, thank you for making it engaging and challenging for students

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-b…

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

Introducing the 50 finalists for the 2026 #ToolsCompetition! Selected from 1,400+ teams, these innovators are tackling some of the biggest challenges in K-12 and postsecondary learning. Finalists will compete for more than $3 million. tools-competition.org/26-finalists/

We are pleased to announce PhET’s inclusion on the @unicef Learning Cabinet! 🌍 Back with strong evidence from 13,000+ independent studies, PhET transforms how students engage with STEM, improving access, skills and attitudes Learn more learningcabinet.org/tool/phet-inte… #EducationForAll

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/simulations… #PeriodicMotion #iTeachPhysics

"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/journals/… #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: @phet-global/a-legacy-in-motion-with-phet-in-peru-252307c4b4a4" target="_blank" rel="nofollow noopener">medium.com/@phet-global/a…

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/simulations… #iteachphysics #physics

Models aren't just 3D renderings of cells or planets—they are the mental maps in a student's head. Vivian (Peru ) shows how @PhETsims help teachers reveal that "hidden" thinking and build stronger mental models.

@NicholasKougias We are glad you’re diving into Build a Nucleus! Let us know which decay path your students find the most surprising!

@PhETsims I've used PhET simulations for years in my classroom, though I'm looking forward to trying this one out as I haven't used it. It seems useful. I like how it shows the stability of nuclei, the type of decay, and their respective half-lives, helping students grasp nuclear concepts.

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/simulations…

“When students are taught not to be afraid of mistakes, they see them as an opportunity to investigate and improve.” See how Ángela uses PhET to foster a fearless classroom: @phet-global/how-to-combat-the-fear-of-making-mistakes-simulate-92cfec030d6f" target="_blank" rel="nofollow noopener">medium.com/@phet-global/h… #iteachphysics #physics

@DanielNIZERE 🥰 Thank you for spreading the word @DanielNIZERE

PhET simulations give students the chance to interact with science concepts, not just read about them. They explore, test ideas, and learn by doing. And the best part? It’s completely FREE. #STEMEducation #ScienceTeaching #ActiveLearning phet.colorado.edu/en/simulations…
