Cordova Observation Tower: Longest Continuous Fiberglass Staircase in the World

The Cordova Tower is the tallest observation tower in a public park in the Midwest. The observation deck measures 106 feet tall. With 170 steps to reach the top it also features the longest continuous fiberglass staircase in the world.

Location
Cordova Park, Red Rock Lake, Marion County, Iowa

Driving Question

  • How did the engineers build the staircase to the observation deck?

Probing Questions

  • How did the engineers make the fiberglass staircase to be so sturdy?
  • Why did they choose to build the tower here?
  • Why did they choose to build the staircase with fiberglass instead of any other material?
  • Is the tower strong enough to survive the elements of Iowa (high winds, rain, snow)?

Classroom Suggestions

Students could:

  • Conduct a real life design challenge using classroom materials to replicate a structure that can withstand different elements (wind, moisture).
  • Create a rubric to evaluate the quality of the designs. 
  • Test, evaluate and refine their designs.

MS-ETS1-3:

Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success
