Engineering for Earthquake Resistance

Active learning works for this topic because students must physically experience seismic forces to grasp abstract concepts like resonance and energy absorption. Hands-on construction and testing let 6th graders see cause-and-effect relationships between design choices and structural outcomes in real time.

Engineering Design Challenge: Earthquake-Resistant Tower

Small groups use limited materials , index cards, tape, paper clips, straws , to design and build a structure that must survive a simulated earthquake on a shake table (a tray on rollers shaken by hand at a standardized rate). Groups record which design features survived and which failed, then iterate at least once. In the debrief, they identify which real-world seismic techniques their designs unknowingly replicated.

Design a building to better survive a major earthquake.

Facilitation Tip

During the Engineering Design Challenge, circulate with the shake table set to LOW intensity first so students observe failure modes without total collapse.

What to look for

Provide students with a diagram of a simple building frame. Ask them to draw and label where they would add bracing or shear walls to improve its earthquake resistance, explaining their choices in one sentence each.

Gallery Walk: Engineering Failures and Successes

Post images and brief case summaries of notable earthquake events: the 1989 Loma Prieta Cypress Freeway collapse, the Kobe 1995 hospital that stood while adjacent buildings failed, and the Taipei 101 tuned mass damper in action. Students annotate each card with the structural principle at work and connect it to their own tower designs, identifying what they could have done differently.

Evaluate the effectiveness of different earthquake-resistant building techniques.

Facilitation Tip

For the Gallery Walk, assign each student one photo of a real building failure or success to analyze and present to their group.

What to look for

Pose the question: 'If you had a limited budget and could only use wood and cardboard, what is one design feature you would prioritize to make a model building more earthquake resistant, and why?' Facilitate a brief class discussion on student ideas.

Activity 03

Formal Debate: Where Should Earthquake-Resistant Building Codes Be Mandatory?

Provide students with seismic hazard data by US region and the cost differential for earthquake-resistant construction (typically 5-10% more for new builds). Groups argue for or against mandatory codes in medium-risk zones like the Central US. This forces students to support a policy position with quantitative evidence, not just general safety claims.

Analyze how cost and material availability limit the solutions we can build.

Facilitation Tip

In the Structured Debate, provide a simple map of seismic zones and prompt students to cite data from the activity about building performance in those areas.

What to look for

After students build and test their earthquake-resistant models, have them swap with a partner. Each student will use a checklist to assess their partner's design: Did it include bracing? Did it use base isolation principles? Did it show signs of collapse? They will then provide one specific suggestion for improvement.

Think-Pair-Share: The Budget Constraint

Present the scenario: a community wants to retrofit its school for seismic safety but has only 30% of the ideal budget. Students must prioritize which single modification gives the most protection per dollar, reasoning from a provided data table of retrofit options and their costs and effectiveness. Pairs share their trade-off analyses and the class builds a ranked list.

A few notes on teaching this unit

Teachers should focus on iterative testing and redesign, emphasizing that engineering is a process of refinement rather than a single correct answer. Avoid lecturing about formulas for natural frequency; instead, let students discover relationships through controlled experiments with materials like straws, cardboard, and rubber bands. Research shows that middle schoolers grasp seismic concepts better when they connect them to observable phenomena rather than abstract calculations.

Successful learning looks like students applying design principles to build stable structures, explaining why certain features improve earthquake resistance, and revising their designs based on test results. They should articulate trade-offs between cost, materials, and safety during peer discussions.

Watch Out for These Misconceptions

• During Engineering Design Challenge: Earthquake-Resistant Tower, watch for students who assume taller towers will always fail first.

  Use the shake table to demonstrate resonance: build two towers of the same material, one short and one tall, and gradually increase shake intensity to show how the tall tower may sway more but not necessarily collapse if frequencies are mismatched.

• During Engineering Design Challenge: Earthquake-Resistant Tower, watch for students who think rigid towers are safest.

  Provide identical materials for both rigid (taped-solid cardboard) and flexible (jointed straws) towers. After testing, have students compare how each design absorbs or redirects energy, noting where rigid structures crack or topple.
