If you’re looking for the source, it’s from the Tom Chapin children’s album Mother Earth, which you can find on Amazon.com. The whole album has great stuff for kids–lots of catchy learning songs.

The original Tom Chapin version of the lyrics goes:

(Each group joins after two rounds of the group before it until all groups are singing together. Then the groups end one at a time in reverse order, until it comes back around to just the baritone “wheel in the water” verse.)

“Wheel in the water go round and round, wheel in the water go round…”

“Water rain down, down, trickle trickle down, down to the ocean, trickle trickle down…”

“See the vapors rise, see them cloud the skies…”

“Clouds rain down, thunder and lightning sound…”

“Spring bubble bubble up…”
