Learning Science in song

What do you do when a colleague asks "What is the second law of thermodynamics"? In our office two people go straight to Flanders and Swan. This is quickly followed with the suggestion of Monty Python for astrophysics (or the universe at least) Then yet another of the classics with Tom Lehrer on chemistry (more specifically Chemistry) Which then led to a suggestion for zoology, about which I'm not so sure about Bad enough, but it is also a place where you don't want to use a greengrocer's apostrophe.
