Teaching Chemistry? Try Our New Sim Alignment Guide


Teaching chemistry? To help you find the best simulation for teaching a specific topic in chemistry, we’ve put together this new preliminary guide that gives you a line up of specific simulations (and supplemental simulations) for topic areas in the general chemistry curriculum.

Want to share suggestions of other PhET sims you use for teaching chemistry topics? Let us know at the PhET Help Desk at

Improved Fluid Pressure and Flow

Fluid Pressure and Flow

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

Thank you Bernard!

PhET Attends NCTM Conference in Denver

Graphing Lines

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!
