I've made some new additions to the Physics Video Padlet, based on links that have been sent to me by colleagues and students over the last few months - including a few links I've picked up from following the always informative @kelleherscience on twitter.
There's a new video of an easily copied demonstration of the effect of wavelength and grating constant on an interference pattern - which links in with another on leaving cert derivations.
There is also this: on Olber's Paradox (why it gets dark at night) - and a link to several hundred great videos from the BBC Science in Action on a range of scientific topics.
Older videos that I enjoy also linked to there include.....
The Man who Tried to Fake an Element. The story it tells is really interesting, but perhaps most usefully, it gives a great overview of particle physics over the first 15 minutes that I think most students and many teachers (or at least me) could learn from.
This from David Hockney, which I always use a little of to finish up our study of optics. It explains his belief that the renaissance artists were all projecting real images onto a screen and painting over those, making the incredible realism of their work a little easier to understand: BBC David Hockneys Secret Knowledge 1of2 DivX MP3 MVGForum - YouTube
And this famous video is great at showing students the connection between the physics we learn in class and the music they might listen to themselves: CYMATICS: Science Vs. Music - Nigel Stanford - YouTube
Or this one, which a student shared with me a few years ago and which I find very useful when talking about colour mixing and how the eye works: How Color Blindness Works - YouTube
