Some decades ago, wonderfully done movies were put together that seem to have no equivalent today in terms of production, scripting and graphics, at least that I can find - nor can I find anyone who sells them. I ask if anyone has good DVD's of the following productions (I have VHS tapes made from yellowed, jumpy, old 16mm films) that I could obtain copies of for classroom use - or knows where I could purchase them:
Rocks that Form on the Earth's Surface
Rocks that Originate Underground
The Rock Cycle
Fire Under the Sea.
