We are currently replacing the remaining Flash objects (.swf) with .mp4.
For an audiovisual introduction to understanding the structure and navigation of Physclips see What is Physclips?
On Designing educational animations, we list some of the advice given in the literature, and show how some examples from Physclips would appear with and without these principles.
Some support pages, together with the audiovisual introduction, have been translated into Chinese and can be accessed here.
For some primary school resources, see Glimpses of Science.
