I often ask this question at TeachMeets – if the internet went on fire, what one resource would you save. As a full time science teacher, my own answer used to be PhET – especially the Circuit Construction Kit. Some of my physics disapprove strongly, but over the past few years it has helped me more than almost anything to get the germ of an idea, of what’s going on in an elctric circuit, planted more clearly into students’ minds.

Have a go (and please don’t tell me if set the dog on fire).
