Skyscrapers are one of the most glorified products of Civil Engineering and contain an interesting history of progress and development. In this lesson, the students will learn about the history of the world's tallest free standing structures and the basic design principles behind their success. Students will build their own newspaper skyscrapers with limited materials and time, trying to achieve a maximum height and the ability to withstand a "hurricane wind" force. Discussion will concentrate on materials, forces that a skyscraper needs to withstand, and basic structural design.

Video describes what gravity is and how it operates between two masses. Followed by a short quiz and a list of additional resources to explore. [4:44]

Through a series of activities, students discover that the concept of mechanical advantage describes reality fairly well. They act as engineers creating a design for a ramp at a construction site by measuring four different inclined planes and calculating the ideal mechanical advantage versus the actual mechanical advantage of each. Then, they use their analysis to make recommendations for the construction site.
