The Physics Classroom

Here's another website but it's for a physics classroom.

There are a lot of animations and classroom resources that you can use as a class, which is great. Make use of this since it's a pretty comprehensive site and covers a good spread of tough concepts that students have trouble with (like graphing motion).

Possible problems: the site may freeze your browser when you use the interactive flash tutorials. Some of them ask for your name and when you run through the animation, you may encounter pop-ups and freeze your browser. I'd recommend trying more sites and using this site in a separate browser.

The link has been added to Earth/Physical Science as Flash - The Physics Classroom.

Enjoy and good luck!
