Earth Science ROCKS.
If a student can sing this song, I think they should get an automatic "A" in Earth Science... and in Music class... and perhaps a role in the Drama Class' performance of The Pirates of Penzance.
I would have had a LOT more fun in high school science if my teacher could sing this to the class.

Links from the last couple days have been lifted from Neil Gaiman's blog (his link is always in the column to the left.) Neil is the author of the award-winning Sandman comic book series, several incredible novels, a few impressive children's books, collections of short stories, radio plays, and screenplays for the BBC miniseries Neverwhere -- but he also finds the time to write a damn fine blog.
Thanks for the links, Neil!
