OVERVIEW FOR THE TEACHER
The Scrambler incorporates into its mechanism several simultaneously occurring rotational motions.
These serve to heighten dimensions that have already been discussed - circular motion, distance
traveled, and speed - so that the rider experiences more of a “thrill.” When working with the Ferris
Wheel and the Boom Ride, students were introduced to some of the concepts involving gears,
especially those of ‘gearing-up’ and ‘gearing-down.’ The Scrambler is yet another ride that involves
gears, but these are quite sophisticated so as to produce the ride’s unique motion. Much like the
Carousel (Lesson 7), the gears on the Scrambler are not only responsible for the main circular motion
of the large arms, but also for the motion of the smaller ones (Lesson 6).
