pure chemistry

PERIODIC VIDEOS is my absolutely most favourite science resource online. The wonderful University of Nottingham Chemistry department have created a video for each element in the periodic table. Engaging and educational these are a great resource to get students excited about science.
PS: I can't resist also sharing this fab video from the EU about chemical bonds, wouldn't it be great to get students to re-construct this?
