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 an iPad app and an Android app that each allow native, offline use of all of our HTML5 sims. Both versions are $0.99 and proceeds fund more HTML5 sim development.

Both apps can be volume purchased by schools or other organizations looking for multiple licenses.
iOS Volume Purchase Program
*Android Managed Google Play
*Buying apps that support bulk licenses is currently available to customers in the U.S. and Canada.

Specific steps for bulk purchasing the PhET Android app can be found here: https://phet.colorado.edu/en/help-center/running-sims/android#q52-header

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.
