Chain Reaction is the STEM song from the episode Dinosaur Parade. It is performed by Scott Krippayne, and plays as Blaze and Zeg observe various chain reactions after saving the dinosaurs from the construction site. It also plays in Sparkle's Big Rescue after Sparkle used various chain reactions to help her jump over the lava.
The energy from a single action
It causes something else to happen
That sets another, a thing in motion
And then it keeps on goin', goin', and goin, and goin'
Chain, ch-chain, ch-chain reaction
Like dominoes knockin' each other down
It's a chain, ch-chain, ch-chain reaction
And one by one, they hit the ground
You set, set it off and let it go
Like a snowball that just gets on a roll
Picking up steam in rows and rows
'Cause one thing leads to another
