The Eiffel Tower, designed by
Gustave Eiffel, was an
incomparable engineering feat
when it was erected in
preparation for the Universal Exposition of
1889.
It only took five months to build the foundations and twenty-one to finish assembling the metal pieces of the Tower.
March 15, 1888 September 15, 1888 December 26, 1888 March 12, 1889
The assembly of the 300 meter tower was a marvel of precision, as all chroniclers of the period agree. (Imagine a
tower taller than 3 football fields, end to end.) The construction work began in January 1887 and was finished
on March 31, 1889.

Tower is basically composed of two parts:
- a base, which is a sort of sturdy stool, standing on 4 main pillars, and
- a tower firmly attached atop.
The pillar base allows the Tower to withstand the swaying wind forces.
Because the basic structure composed of laminated iron is visible, the Geometry is clear. Let’s explore this marvel, looking for the MATH!
Use your Math terms to describe what you see…

Your Challenge!
You will work with a Design
and Construction
Crew to create a new Tower, using only
toothpicks and glue.
Your Tower base may not have more than 4 supports at the base.
Your Tower base must be set on a 12” x 12” tile.
Your Tower must be structurally able to support a tennis ball at the top.
Your Tower must reach minimum height requirements.
Base: 10” x 10” squareHeight: 30 inches
