Thanks for your patience during our system maintenance.

Have you received our May 2013 newsletter? Learn about two big initiatives that we’re working on over the summer: a new “Teach with PhET” companion website designed for teachers and other education professionals, and the development of the next-generation of PhET simulations.

Join us and support PhET. Your dollars will go directly to helping with these important improvements. Donate to PhET’s End-of-School Campaign today.

A big Shout Out to Bernard LaCour who pointed out a bug in Fluid Pressure and Flow. As soon as we heard about the problem, we addressed the issue and posted the fix. We know how important it is to correct any issue with our simulations. So if you find a problem, please let us know through the PhET Help Desk at phethelp@colorado.edu.

Thank you Bernard!

With Spring finally here and rainbows soon to follow, explore PhET’s Bending Light simulation and learn why rainbows are ROYGBIV.

Thank you to everyone who stopped by our booth at the National Council of Teachers of Mathematics Annual Meeting in Denver this past April. We thoroughly enjoyed meeting with all the math teachers and having the opportunity to share the awesome free resource that is PhET! In addition, we were grateful for being a featured component of several talks, such as Mark Roddy’s discussion about Mathematizing the World. We look forward to the next NCTM Conference in New Orleans, April 9-12, 2014, and meeting even more great educators. We are excited to expand our suite of math simulations, so look for more coming soon!

We’re excited to announce our very own Trish Loeblein, PhET K-12 Specialist, was honored to receive the ACS 2013 Colorado High School Teaching Award.

Trish has taught all levels of science including chemistry, physics and math, including many AP courses. Trish was recognized because she “brings an enormous energy to the classroom” and “goes out of her way to teach difficult concepts in a more tangible manner, a skill which is necessary for challenging chemistry and physics courses.”

Congratulations Trish!

We’re excited to add our last Java-based simulation, Energy Forms and Changes. Explore how heating and cooling iron, brick, and water adds or removes energy. See how energy is transferred between objects. Build your own system, with energy sources, changers, and users. Track and visualize how energy flows and changes through your system.

Thanks for your patience during our system upgrade.

Right now user donations are our key source of funding towards converting simulations to HTML5 and bringing them to iPad and Android tablets.

So please consider donating today. And, thank you to those of you who have already donated. Your support will help keep our work funded through the summer.
