From BoingBoing:
Here Comes Science contains a broad, inclusive and thought-provoking tour through science in all its facets. Songs like "Science is Real" (which explains how scientific beliefs are different from beliefs in unicorns and other beliefs formed without rigorous testing) and "Put It To the Test" (possibly the best kids' song ever written about falsifiablity in hypothesis formation) cover the basics, the big Philosophy of Science questions.
Then there's songs for all the major disciplines: "Meet the Elements," "I am a Paleontologist" (also delving into the joys of a science career), "My Brother the Ape," "How Many Planets," and the diptych formed by "Why Does the Sun Shine?" (stars considered as superheated gas) and "Why Does the Sun Really Shine?" (stars considered as superheated plasma) -- these last two are a brilliant look into how different paradigms have different practical and theoretical uses. "Photosynthesis," "Cells" "Speed and Velocity" -- you get the picture.
Finally, there's some jaunty little numbers about technology: "Computer Assisted Design," and "Electric Car" and one genuinely silly and delightful track, "The Ballad of Davy Crockett (In Outer Space)." (I haven't enjoyed an "in outer space" reworking of a beloved classic so much since "Josie and the Pussycats In Outer Space").
You can find Here Comes Science at Amazon for around $15.
