Earthquake Impacts and Mitigation Strategies

Active learning transforms abstract seismic data into visible, tangible experiences that clarify how earthquakes shape landscapes and communities. Students engage directly with structural stability, global variability, and human response, which builds deeper understanding than passive study alone.

Activity 01

• Outdoor Investigation Session
• 45 min · Small Groups

Shake Table Challenge: Model Testing

Provide students with materials like spaghetti, marshmallows, and clay to build small-scale structures. Test them on a DIY shake table made from a tray and motor. Groups measure damage levels and redesign for resilience, recording improvements.

Evaluate the effectiveness of different building codes in earthquake-prone regions.

Facilitation Tip

During the Shake Table Challenge, remind students to test one variable at a time so they can isolate the effect of building design on collapse resistance.

What to look for

Facilitate a class debate using the prompt: 'Which is more effective in saving lives during a major earthquake: advanced building codes or comprehensive community preparedness drills?'. Ask students to cite specific examples and evidence to support their arguments.

Activity 02

• Jigsaw
• 50 min · Small Groups

Jigsaw: Global Case Studies

Assign groups one earthquake case, such as Haiti 2010 or Japan 2011. They research impacts and mitigations using provided sources, then rotate to teach peers and compile a class comparison chart.

Analyze the socio-economic impacts of a major earthquake on a developing country.

Facilitation Tip

In the Jigsaw, assign each expert group a specific case study section to present, ensuring all students contribute to the final synthesis.

What to look for

Present students with a case study of a fictional earthquake impacting a city. Ask them to identify three primary impacts (e.g., structural collapse, fires) and three secondary impacts (e.g., utility disruption, displacement) they would expect to observe, and briefly explain why.

Activity 03

• Outdoor Investigation Session
• 40 min · Pairs

Design Lab: Preparedness Plan

In pairs, students create a poster or digital plan for a fictional earthquake-prone Singapore neighborhood, incorporating building codes, drills, and warning systems. Present and peer-review for effectiveness.

Design a community preparedness plan for an earthquake-prone area.

Facilitation Tip

For the Design Lab, provide a limited set of low-cost materials so students focus on smart engineering rather than expensive solutions.

What to look for

Students work in small groups to draft a section of a community preparedness plan (e.g., communication strategy, evacuation routes). After drafting, groups exchange their section with another group. Peers provide feedback on clarity, feasibility, and completeness using a provided checklist.

Activity 04

• Outdoor Investigation Session
• 35 min · Whole Class

Debate Circle: Strategy Effectiveness

Divide class into teams to argue for or against specific mitigations, like retrofitting vs new codes, using evidence from cases. Whole class votes and reflects on key factors.

Evaluate the effectiveness of different building codes in earthquake-prone regions.

Facilitation Tip

During the Debate Circle, assign roles in advance so students prepare arguments and counterarguments before the discussion.

A few notes on teaching this unit

Teach this topic by moving from concrete to abstract. Start with hands-on modeling so students feel seismic forces, then use case studies to connect those forces to human outcomes. Avoid overwhelming students with too many variables at once. Research shows that inquiry-based labs and structured debates build both conceptual clarity and critical thinking, especially when students analyze real-world examples side by side.

Students will explain how local conditions influence earthquake impacts and justify mitigation strategies using evidence from models, case studies, and design work. They will also evaluate trade-offs in preparedness and recovery, particularly in resource-limited settings.

Watch Out for These Misconceptions

• During the Shake Table Challenge, watch for students who assume all models will perform the same regardless of base material or design.

  Ask groups to compare how different soil types (sand vs. clay) affect building stability during shaking, using their shake table results to revise initial assumptions.

• During the Jigsaw, watch for students who assume that wealth alone determines earthquake resilience.

  Have expert groups prepare a slide on one low-cost mitigation strategy used in their case study, such as reinforced masonry or community drills, to counter overgeneralizations about cost barriers.

• During the Design Lab, watch for students who believe only expensive technology can save lives.

  Require each group to include a public education component in their preparedness plan, such as a simple brochure or drill schedule, to highlight non-structural solutions.
