Try the newly published tablet-compatible John Travoltage simulation.
Make sparks fly with John Travoltage. 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.
Has PhET been slow or simply not working?
We’re actively working on the problem and hope to have it resolved soon. In the interim, if you’re planning on using PhET in your classroom, please consider downloading the simulations in advance to ensure that you and your students can work on PhET sims.
Please e-mail [email protected], or post a Facebook or blog message, to let us know when you are having a problem.
Thank you SPIE for featuring PhET in the SPIE Newsroom. In the video, see Director, Kathy Perkins, speak about how PhET’s science simulations facilitate STEM education and develop problem-solving skills.
We’re excited to present the HTML5 version of Build an Atom. Now with your fingers, you can build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
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!
