Try the new #HTML5 Color Vision simulation. Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

Students will learn to:

• Determine what color the person sees for various combinations of red, green, and blue light.
• Describe the color of light that is able to pass through different colored filters.

For software developers: our educational HTML5 apps & libraries are open source and ready to use in your projects: http://bit.ly/phet-development-overview

Learn how to:

1. Check out the PhET HTML5 libraries and simulations from GitHub
2. Create new simulations
3. Understand & customize code for our simulations
4. Submit bug fixes for our simulations
5. Embed a PhET simulation in your own website
6. Use powerful libraries for rendering, audio, touch/mouse/pen input, geometry, MVC, UI and more.
7. Communicate with PhET developers and others developing with PhET libraries

Hope to see you there!

Try the new HTML5 Balancing Chemical Equations simulation! How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas. Students will learn to:

• Balance a chemical equation.
• Recognize that the number of atoms of each element is conserved in a chemical reaction.
• Describe the difference between coefficients and subscripts in a chemical equation.
• Translate from symbolic to molecular representations of matter.

Thank you American Association of Chemistry Teachers for your generous donation that supported the development of the new HTML5 Balancing Chemical Equations.

PhET needs your help! If you’re an educator, parent, student, STEM supporter or a company, please support our campaign to bring the popular Circuit Construction Kit to HTML5 compatibility. Any amount helps — minimum donation is $10. Donate now to help speed the conversions.

Get the sparks flying for the new school year with the John Travoltage simulation. Wiggle Johnnie’s foot and he picks up charges from the carpet. Bring his hand close to the door knob and get rid of the excess charge.

Good luck to both students and teachers for the upcoming year!

Try the HTML5 version of Build an Atom to refresh your knowledge of the periodic table. With your fingers, build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test what you’ve re-learned!

We’re excited to add yet another HTML5 simulation to our growing touch/tablet-compatible mathematics collection–just in time for the 2014-2015 academic year. With the new HTML5 Graphing Lines, explore the world of lines. Investigate the relationships between linear equations, slope, and graphs of lines. Choose between the “Slope,” “Slope-Intercept” and “Point-Slope” tabs. Then challenge your knowledge in the “Line Game”!

Try our new HTML5 tablet/browser-compatible Fraction Matcher simulation. A great way to improve fraction skills for the younger student. Match shapes and numbers to earn stars in this fractions game. Students can challenge themselves at different levels, collecting stars as they improve their fraction skills. Choose between the “Fractions” and “Mixed Numbers” tabs for more learning fun.

Thank you W. W. Norton & Company for your support of PhET’s chemistry simulations. Your generous donation will go directly to bringing more HTML5 simulations to students around the world.

Hot outside? Looking for something that will cool you off?

Try the Under Pressure simulation and explore pressure under and above water. See how pressure changes as you change fluids, gravity, container shapes, and volume.
