Winter break is a great time to look for new teaching resources.  Here is an excellent one from the “Physics Education” Google+ group:

There are a huge number of physics simulations here, all developed by Frank McCulley, a high school physics teacher in New Jersey.

We have been looking for a good way to plot data for the “Constant Speed Motion” toy car lab we do at the beginning of the year, and his “Quick Graph and Linearization” tool is exactly what we needed.  It will work on any device with a browser, and it gives a linear best fit line way more quickly than Microsoft Excel.

Let us know in the comments below if you have tried any of Frank’s simulations or tools, or have any other recommendations for great sites!
