A Victim of Gravity is the song on the Science Rock volume. The theme is gravity. The song was sung by the Tokens in 1978, being the only "Schoolhouse Rock" song to be sung by a band.
There are historical references, as it mentions Galileo discovering what he didn't know was gravity, and Isaac Newton discovering both gravity and its name when an apple fell on his head from a tree he sat under, and his theory.
This song teaches about the universal law of gravity.
The main character is unnamed, but it is shown that his girlfriend's name is Mary Jean.
