In 2005, when discussing the proposed border wall between the United States and Mexico, then- Arizona governor Janet Napolitano said, “You show me a fifty foot wall. I’ll show you a fifty-one foot ladder.” Politics aside, would a 51-foot ladder actually be long enough to climb a 50-foot wall?
In this lesson, students combine OSHA’s recommendations for ladder safety with the Pythagorean Theorem
(Grade 8) or trigonometric ratios
(Geometry) to explore how high you can really climb.
