The little engine that may well work --- today
An exercise for kids of all ages to understand connections. Divide the class into ten parts. Have each group move in a different way to exemplify these parts of a machine in motion.

10 roles of machinery:

Parts of the engine | motions

Fuel tank | sitting
fuel pump | pumping action
battery | hiss, clap and move in a jump
wires to rotor | stretch and turn
Spark Plugs | snap finger 0r clap hands
Piston | deep knee bends,

flywheel | move arms in a circle
throttle | bend at the waste
exhaust | run in place
Muffler | isometric exercise

Steam engine -- double acting:

Aircraft piston & power steering:
