I bought this album for my little sisters back in the 80s. They're both in college now, and they still remember it fondly and rate it above the Slugs' "Dirt Made My Lunch." In fact, I'm getting it for them on CD because one of their teachers borrowed their old cassette copy and never returned it! From the incredibly catchy "No Bones Within" ("Head, thorax, abdomen ... I'm talking about our six-legged friends!") through the "Air Cycle" ("What the trees breathe out, we breathe in, trade CO2 for oxygen"), "Adventures on the Air Cycle" is elementary school science made hummable and fun.
