Our project originally focused on physics sims, and was hence named the *Ph*ysics *E*ducation *T*echnology project, or *PhET*. When we branched into chemistry, biology, mathematics and other areas, we decided to keep the name *PhET*, but to no longer describe it as an acronym.

Click the "Embed" button under the simulation you would like to embed. This will bring up a text box of html code that you can copy and paste in order to embed the sim. Flash sims may be directly embedded or linked via an image to launch the sim. Java sims may only be linked via an image to launch the sim.

Some LMS may require you to use "https://" for the URL of the simulation.

We offer apps for both iOS and Android/Chromebook. Please see specific information by platform:

Chromebook
Android phone/tablet
iOS iPad/iPhone

All versions of our apps allow native, offline use of all of our HTML5 sims and proceeds fund more HTML5 sim development.

The PhET HTML5 and Javascript source code lives on the PhET GitHub page. The PhET Java, Flash, and Flex source code lives in a Subversion repository. To get more information about accessing, see the Source Code page.
