The science jukebox is a collection of 18 science songs that I wrote over 8 years.  These songs were main features of my science classes for grades 2-8.  The lyrics are very "meaty" and give the basics of each branch of science-- things like the five types of arthropods, the simple machines, what DNA is made of, classification of marine invertebrates, etc.  The musical styles of the songs are diverse-- everything from sea shanties to rap songs.  The actual recording and production was done completely by homeschooled students in an in-home recording studio. The cdbaby site will let you sample the songs, with no obligation to purchase.
