Don’t Forget to Join Us to Learn About Using PhET Sims for Teaching Balancing Chemical Equations

The ability to balance chemical equations is a foundational skill in chemistry. This week Yuen-ying Carpenter, Emily Moore, and Director, Kathy Perkins will be available to discuss employing guided-inquiry activities along with PhET simulations to teach students skills in balancing chemical equations. Please join the discussion at

Using an Interactive Simulation to Support Development of Expert Practices for Balancing Chemical Equations

Join the Virtual Conference: “Interactive Visualizations for Chemistry Teaching and Learning”

Want to learn more about how to use visualizations—animations and simulations— in chemistry education? This conference will discuss a range of topics in the study of chemistry visualizations, providing insights into: problem solving practices; student ownership; multi-model learning; and inclusive chemistry learning. Each week there are two “assigned” papers for reading, and then an open discussion period where participants can post questions and engage in a public discussion with the authors. Join us for some or all of the conference:

Time: Friday, May 8th 9 PM through Friday, June 4th 9 PM

PhET will be featured during:

May 15-21
Using an Interactive Simulation to Support Development of Expert Practices for Balancing Chemical Equations
Yuen-ying Carpenter, Emily B. Moore, and Katherine K. Perkins

May 29-June 4
Designing Accessible Interactive Chemistry Simulations
Emily B. Moore

Honoring Our Own PhET K12 Specialist: Teacher Trish Loeblein


Congratulations to Conifer Chemistry Teacher and PhET K12 Specialist, Trish Loeblein, on her retirement from teaching!

Trish has been a dedicated teacher for over 30 years, and a member of the PhET team for the last 10, helping design over 50 simulations and contributing over 130 guided-inquiry-based activities along with many teacher resources! Her activities are the most popular in our database with more than 900,000 downloads in the past year. In addition, she has run numerous teacher workshops and webinars, both locally and nationally. Over her many years of teaching, Trish has touched thousands of students focusing on their learning, specifically understanding and learning to think, NOT just memorization.

Thanks Trish for inspiring a generation of students! And while the students will certainly miss you in the classroom, we are excited that you will continue to work part-time with PhET! #ThankaTeacher

#ThankaTeacher Week: Thanks to Martin Veillette

In honor of #ThankaTeacher week, PhET would like to thank Prof. Martin Veillette. Martin comes to us from Berea College where he is an associate professor of physics, teaching courses across the physics curriculum, from astronomy to quantum mechanics. He has been an avid user of PhET simulations as an instructor and this year he has been with us working as a software developer, learning the tools of the trade during his sabbatical leave. During his time at PhET, he partnered with Amanda McGarry to create the brand new #HTML5 sim Least Squares Regression. He also worked on the upcoming #HTML5 Charges and Fields and Pinko Probability.  When he’s not teaching physics, you can see him in “creeking” in the streams of Kentucky. Thanks Martin!

Water Waves, Jump Rope Waves: Explore with Wave on a String


Use the #HTML5 Wave on a String to learn about wave properties. Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open.

PhET at the “Oscars of Innovation in Higher Education”

Oscars of Innovation


Recently PhET attended the Reimagine Education Conference for “outside-the-box” approaches to higher education at the Wharton School of the University of Pennsylvania. PhET was honored to share the overall prize with PaGamO from National Taiwan University. Read about other honorees and the conference at

New #HTML5 Molecules and Light


Try the new #HTML5 Molecules and Light simulation. Do you ever wonder how a greenhouse gas affects the climate, or why the ozone layer is important? Use the sim to explore how light interacts with molecules in our atmosphere.
