Two wonderful video projects by the University of Nottingham:

Sixty Symbols, short documentaries about symbols used in physics and astronomy. Includes YouTube annotations in a few cases. Accessible and delightful.

And: The Periodic Tables of Videos, short documentaries about each element in the periodic table.
