In the late 1950’s and early 1960’s, Hy Zaret and Lou Singer produced a set of 6 albums featuring songs about various aspects of science. They were wonderful albums, and I remember hearing the songs when I was a kid. Tom Glazer sang on three of the albums, and recently, They Might Be Giants recorded the song “Why Does the Sun Shine?” which was originally on the “Space Songs” album.
Jef Poskanzer has encoded MP3s of the songs on the original albums, and he has set up a Singing Science section of his site to collect the files and provide a mailing list to discuss them.
After finding Jef’s site, I have a brand new set of CDs to torture my kids with on the drive to school. Geek parents have geek kids, so I’ll probably tire of the songs before the kids do.
