Today's the DAY!!! Join the #FREE #EarlyAccess period for PhET Studio right now! Go to phet.colorado.edu/studio to get started crafting your own presets. We can't wait to see what you create! #LaunchDay #PhETStudio #InteractYourWay

Free Interactive Science Simulations for Students. #tech #aitools #AI #AI2026 #AITools2026

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

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…

@ria_commissions @ria_commissions That sounds like a productive session!

Can you give us a creative line, a "sim-pun," or a joke featuring one of our PhET sims? We’ll start with our favorite skater: "I’m on a total emotional roller coaster, but at least my Total Energy remains constant!" 😎 Drop your best lines in the comments! phet.colorado.edu/en/simulations… #iteachphysics #physics #PhETlines

"I now promote discovery-based learning more effectively." Vivian’s journey with the STEM Mentors for Impact program shows how the right tools can transform teaching practice and student outcomes.
