What is something interesting and interactive I can teach to my class that is about ferris wheel?

George W. G. Ferris, a U.S. engineer from Galesburg, Ill., designed and built the first such wheel for the World's Columbian Exposition held in Chicago in 1892. This wheel was 250 ft (76 m) in diameter and carried 36 cars with a seating capacity of 40 passengers each; its total weight was 220 tons. Depending on grade level, you can do all sorts of projects about the science needed to construct and operate them or the history of why it was built and the reasons behind its popularity.
