Lesson 7: Constructions that Make You Wonder: Iconic Successes and Failures

What factors contribute to a structure fulfilling its purpose over centuries?

How do specific material breakthroughs or engineering principles prevent structural failure?

Why should society care about the maintenance and updating of historical infrastructure?

ETS1: Engineering Design (Developing and using models; constructing explanations and designing solutions).

ETS2: Links among engineering, technology, science, and society (Mastery over natural forces).

Synthesizing information from multiple credible sources, interpreting technical information in informational texts, and utilizing evidence to support claims in a formal presentation.

Description:
Day 1: Selection and Preliminary Research. Students choose a structure that "makes them wonder" from provided lists of iconic buildings (e.g., Burj Khalifa, Cologne Cathedral) or bridges (e.g., Golden Gate Bridge, Manhattan Bridge). Alternatively, they may select a notable structural failure like the Francis Scott Key Bridge. They begin researching the people responsible for its construction, its original and changing purposes, and its primary materials.

Day 2: Synthesis and Media Creation. Students develop a 3-4 slide presentation. They must explain the scientific or engineering principles involved (e.g., how Taipei 101 handles earthquakes) and create a "Before & After Technology Meme" that illustrates how a specific breakthrough solved a problem or how a lack of technology led to failure.

Day 3: Presentations. Students present their findings to the class, focusing on the impact of the structure on the construction industry and its lasting legacy.


Purpose: To help students understand the evolution of construction technology and how engineering decisions directly impact modern building practices and public safety.


DOK Level: 4 (Extended Thinking). Requires investigating a complex problem and synthesizing multiple sources of information over an extended period.

Analyzing current events, such as the 2024 collapse of the Francis Scott Key Bridge caused by a container ship impact, to understand structural vulnerability and traffic impact.

Investigation of structures with high symbolic, religious, or national value, such as the Statue of Liberty (National Identity), Christ the Redeemer (Religious/Cultural icon), or the Great Mosque of Djenné (Indigenous architectural styles).

Misconception: Iconic structures are "finished" once built.

Correction: All structures require ongoing maintenance or updates to ensure continued safety and functionality.
Misconception: Failures only occur due to "cheap" materials.
Correction: Failures are often the result of unforeseen external forces, such as the resonance and torsion that affect suspension bridges or extreme environmental loads.

English Learners: Build a word wall with visual flashcards for technical terms; use the "Idioms Table" to bridge literal and metaphorical concepts.

Advanced Learners: Task students with researching specific, complex breakthroughs such as Prestressed Concrete, Twin-Wall Technology, or Cross-Laminated Timber (CLT).

Formative: Check for credible source citations and logical flow in the slide drafts.

Summative: Evaluation of the 3-4 slide presentation and the "Before & After" meme using a 45-point standardized rubric.

Sources: "0.2-Constructions that makes you wonder," "0.4-Science and Engineering Breakthroughs in Construction History," "0.3c-History of Construction".

Technology: Presentation software (Google Slides/PowerPoint), access to Google Maps for location data.

Speaker: Invite a local structural engineer to discuss a recent local construction project and the "engineering principles" applied to its design.
