Today we are learning about gear trains by using the instructions for merry go round
from the red Simple motorized machines sets and the yellow mini sets.
Using the number 7 instructions for the merry go round has G instructions added for motor.
We found out it is importation to follow the instructions closely.
Two versions of merry go round are attached by pulley.
The one with people goes faster when the drive pulley is larger.
