PhET Physics Simulations

From the University of Colorado at Boulder comes PhET Physics Simulations.

Here’s a screen shot from the Gravity Force Lab, which demonstrates the universal law of gravitation:

Each simulation has lesson plans and work sheets associated with it created by other teachers.  These are a mixed bag.  While some of the files provide a quick lesson or a good starting point, others are too advanced or upper level to be useful with my students.
