Logan Whitehurst & the Junior Science Club Flood Control

Making noises in the back seat
Telling me to stop and eat meat
It's a cheat sheet
Covered with a little diagram
Of a heart, it's a chart with the
Parts of the heart all marked
A, B, You can see
Where the ventricles start

(simultaneously with the above part)
The hand is becoming increasingly hard to control
Try to do as the natives do
And be rooted to the spot with my hand on the lever
That controls the rate of flow
It's called flood control
