I first heard about these little videos on Radio 4.  Professor Martyn Poliakoff from Nottingham university has made a short 'video' about every one of the elements in the periodic table.  He was interviewed on PM and was engagingly enthusiatic about it all. Apparently the idea started as a bit of a joke and then blossomed as the potential for teaching and learning became apparent. 

It is quite useful to start with the introductory video, rather than just jump in with an element, because it gives you an idea of who he is and his starting point.  I found him a little eccentric, but with very short exposure to what he has done I have already understood more about the periodic table than I did before.  I hope in time, my children will find them similarly useful.

PS. Since I first looked at this I have discovered that the 'other' periodic table posters he has in his office, like the one about vegetables, or fruit are available from various online shops, not least ebay.  I have yet to find the one about desserts, sadly.
