PhET - Physics Education Technology at the University of Colorado

Logo for PhET - Physics Education Technology at the University of Colorado
A collection of simulations and virtual labs focusing on first-year college physics. An interview with the award winning author can be found in About us at Phet VideoPhET provides fun, interactive, research-based simulations of physical phenomena for free. We believe that our research-based approach- incorporating findings from prior research and our own testing- enables students to make connections between real-life phenomena and the underlying science, deepening their understanding and...

This site is highly recommended for use as either "stand-alone" simulated labs or as an effective instructional aid to class-room lectures. Most of the simulations are well-thought of and illustrate the main physical principles adequately.  The teaching notes provided by instructors who have already used the simulations are noteworthy and helpful.

This suite of applets and associated research are phenominal. I have been using them in my general physics courses for more than 4 years.

You can use the apps in what I call "experimental" mode to try to generate some data and allow students to do their own.

Technical Remarks:

You probably want to download the java applets to avoid difficulties over a slow network, and then have to make sure your computers are setup properly, but once that is done, it is smooth sailing.

Simulations enhance students to learn physics by playing with them.
Time spent reviewing site: Easy to use, and to get to the physics area you are looking to.

The best part about Java/Flash applets is how well they support inquiry-based learning. My student love exploring with them. The Circuit construction kit is the best circuit simulator, hands-down!

Great animations with tons of lessons/handouts to choose from or work from. Covers tons of topics and the students love it!

Technical Remarks:

Animations can be downloaded to be used in your classroom even if you don't have internet!
