Mitigating Natural Hazards

Active learning transforms abstract hazard science into tangible problem-solving, letting students experience how engineering and planning mitigate risks in real communities. When students build, compare, and assess solutions, they move from hearing about hazards to shaping how places can stay safer.

Engineering Challenge: Earthquake-Resistant Building Design

Student teams receive a constrained budget of materials (index cards, tape, marshmallows, toothpicks, straws) and must build the tallest structure that survives a simulated earthquake (shaking the base plate). Teams document their design choices and explain what engineering principles they applied. After testing, they analyze failure modes and modify designs before a second test.

Explain how engineering solutions can mitigate the impact of natural disasters.

Facilitation Tip

During the Engineering Challenge, circulate with a decibel meter to emphasize that the goal is reducing damage, not achieving zero movement, so students focus on measurable risk reduction.

What to look for

Present students with a scenario: 'A coastal town is planning for increased hurricane intensity.' Ask them to list two engineering solutions and one land-use regulation that could help mitigate risks, and briefly explain the trade-off for each.

Case Study Comparison: Two Earthquakes, Very Different Outcomes

Students read summaries of the 2010 Haiti earthquake (7.0 magnitude, 160,000+ deaths) and the 2011 Japan earthquake (9.0 magnitude, roughly 20,000 deaths). They complete a comparison chart analyzing building codes, early warning systems, emergency response capacity, and economic factors. The class discusses what the data reveals about the role of preparedness vs. magnitude in determining death toll.

Analyze the effectiveness of different preparedness strategies for earthquakes or hurricanes.

Facilitation Tip

For the Case Study Comparison, assign each pair a specific factor (building codes, wealth, early warning) to track so they see how these variables shape outcomes, not just geography.

What to look for

Facilitate a class discussion using the prompt: 'Imagine your community is at risk from earthquakes. What are the most important preparedness strategies we should implement, and why are they more effective than simply building stronger houses?'

Community Risk Assessment: Your Region

Students research the primary natural hazard risk for their actual community using FEMA's National Risk Index or USGS hazard maps. They identify the top hazard, find one engineering solution currently in place, identify one gap in current preparedness, and propose one specific improvement. Students share findings in a structured gallery walk that covers multiple US regions.

Design a community plan to reduce risks from a specific natural hazard.

Facilitation Tip

In the Community Risk Assessment, require students to interview a local stakeholder or use census data to ground their plans in real community needs and constraints.

What to look for

Students draft a one-page community plan for a specific hazard. They then exchange plans with a partner and use a rubric to assess: 1) Are at least two mitigation strategies included? 2) Is the target audience for preparedness clearly identified? 3) Are potential trade-offs considered?

A few notes on teaching this unit

Teach this topic by grounding abstract hazards in local relevance, using real-world cases to show that mitigation is iterative and value-laden. Avoid framing engineering as a binary safe/unsafe problem; instead, emphasize thresholds, trade-offs, and the role of policy in shaping who is protected. Research shows students grasp risk reduction better when they design for specific communities rather than generic scenarios.

Successful learning looks like students applying hazard science to design, evaluate, and refine mitigation strategies, not just reciting facts about natural events. They should articulate trade-offs, identify vulnerable populations, and connect physical science to social responsibility in their plans and discussions.

Watch Out for These Misconceptions

• During Engineering Challenge: Earthquake-Resistant Building Design, students may assume their structure will survive any quake if it survives the initial test.

  Use the shake table’s force settings to set a clear design threshold in advance. After testing, ask students to identify the exact magnitude at which their structure failed and discuss why engineers set thresholds based on expected—not maximum—hazards.

• During Case Study Comparison: Two Earthquakes, Very Different Outcomes, students may believe that wealth alone explains disaster outcomes.

  Provide data on building codes, early warning systems, and emergency response times. Have students categorize findings into infrastructure, policy, and socioeconomic factors, then rank their relative impact on survival rates.
