A few years ago, I helped make a bunch of films intended for use in GCSE Science lessons. I was reminded of their existence when a friend of mine stumbled across them on the internet. Below is one about Nuclear Fission which I particularly like (although I’d probably have made it, and the others, differently if I had had editorial control). You can see the whole collection here.
Thanks Alom, really useful selection of videos - bookmarked. I like the evolution of the eye video. My bookmarks for science resources are getting rather disorganised - I must sort them out!
