Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation!

We’re excited about our new grant proposal that we submitted to the Dept. of Education on building and studying math simulations, specifically for middle school. The funding would significantly expand our offering math offerings so keep your fingers crossed!
Have you tried our new HTML5 version of Balloons and Static Electricity?
Why does a balloon stick to your sweater? Rub a balloon on a sweater, then let go of the balloon and it flies over and sticks to the sweater. View the charges in the sweater, balloons, and the wall.
Try the new next-gen version of our popular Gravity Force Lab — now for touch and tablets! With a touch of your finger, experience how the gravitational force that two objects exert on each other changes as you alter their properties. What happens as you increase the mass of the objects? What happens as you move them farther apart?
We are so excited to release our next-gen HTML5 sims—just in time for the 2013-2014 academic year! These HTML5 versions not only are touch and tablet optimized but also have built-in flexibility that will enable us to easily facilitate future improvements, including enhanced 3rd-party customization and assessment abilities.
To learn about the new features, and the Future of PhET, watch the video on the right-side of the new (and temporary) “HTML5 HomePage”. The video gives tips on how to use the sims, as well as a glimpse to see what’s coming.
Do you like our new logo? We hope that the new logo reflects our mission to advance science and math literacy worldwide by making STEM active, engaging and most of all, fun!

P.S. We are working on updating the logo on our donation page.
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 firstname.lastname@example.org.
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 email@example.com.
Thank you Bernard!
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.
We’ve been busy working on making our simulations iPad compatible. We hope to have a number of them ready over the summer so they will be available for the 2013-2014 school year, including Build an Atom, Concentration, and Ohm’s Law.
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.
