Active learning ideas

Earthquakes & Seismic Risk

Active learning works because earthquakes and seismic risk are dynamic concepts that benefit from hands-on exploration. Students need to connect abstract tectonic processes to real-world impacts, which is best achieved through collaborative tasks and problem-solving scenarios rather than passive listening.

Jigsaw: Earthquake Components

Assign expert groups to research causes, measurement, effects, or mitigation. Each expert teaches their topic to a new home group, using visuals and examples from Canadian events. Groups synthesize findings into a class infographic.

Analyze the factors that contribute to the varying intensity and damage caused by earthquakes.

Facilitation Tip

In the Jigsaw Protocol, assign each expert group a specific fault type or measurement scale to research, then require them to teach their findings to their home groups using clear visuals or analogies.

What to look for

Present students with a scenario describing an earthquake's effects (e.g., 'Buildings collapsed, power lines down, widespread panic'). Ask them to identify at least two factors that likely contributed to the severity of the damage and one potential mitigation strategy that could have reduced it.

Shake Table Engineering Challenge

Provide materials like popsicle sticks and clay for students to build model structures. Test designs on a simple shake table, varying earthquake intensities. Groups analyze failures and redesign using seismic principles.

Evaluate the effectiveness of different building codes and urban planning strategies in earthquake-prone regions.

Facilitation Tip

For the Shake Table Engineering Challenge, demonstrate how to adjust variables like soil type or building height by testing one at a time, so students can isolate the impact of each factor on structural stability.

What to look for

Facilitate a class debate: 'Should governments mandate the most expensive seismic retrofitting for all older buildings in high-risk zones, or is a phased approach based on building type and occupancy more practical?' Encourage students to cite economic and safety considerations.

Risk Mapping Simulation

Distribute base maps of Canada and Ontario. Students plot fault lines, historical quakes, and population centers, then overlay mitigation zones. Discuss predictions for a major event in whole-class share-out.

Predict the societal and economic impacts of a major earthquake in a densely populated area.

Facilitation Tip

During the Risk Mapping Simulation, provide students with blank maps and colored pencils to mark high-risk zones, then have them justify their choices using data like historical earthquake records or building codes.

What to look for

Ask students to write down the difference between earthquake magnitude and intensity, providing a brief example for each. Then, have them list one specific challenge faced by urban planners in a seismically active area.

Policy Debate Carousel

Pairs prepare arguments for or against specific building codes or zoning strategies. Rotate to debate at different stations, rotating roles. Conclude with vote and reflection on evidence.

Analyze the factors that contribute to the varying intensity and damage caused by earthquakes.

Facilitation Tip

In the Policy Debate Carousel, assign roles (e.g., urban planner, economist, emergency responder) so students must defend positions grounded in both scientific and societal priorities.

A few notes on teaching this unit

Teach this topic by grounding abstract concepts in concrete experiences. Use analogies students can visualize, such as comparing fault stress to a stretched rubber band snapping, but always clarify where analogies break down. Avoid overwhelming students with too many scales or formulas at once; focus instead on helping them understand the purpose behind each measurement. Research shows that students retain earthquake concepts better when they connect them to familiar places, so incorporate local examples of seismic risk whenever possible.

Successful learning looks like students confidently explaining the causes and effects of earthquakes using precise terminology, applying seismic measurement scales to real data, and designing solutions that address both safety and practical constraints. They should also question assumptions about seismic risk and communicate their reasoning clearly in discussions.

Watch Out for These Misconceptions

• During the Jigsaw Protocol: Earthquake Components, watch for students assuming all earthquakes occur at plate boundaries.

  Have students map global seismic data in their expert groups, then present anomalies like intraplate quakes in eastern Canada. Ask them to explain why these events occur and how they challenge the initial assumption.

• During the Shake Table Engineering Challenge, watch for students believing the Richter scale directly measures damage.

  After testing structures on different surfaces, ask students to compare damage from quakes of the same magnitude on sand versus bedrock. Use their observations to highlight the difference between magnitude and intensity scales.

• During the Policy Debate Carousel, watch for students accepting animal behavior as a reliable earthquake prediction method.

  Provide students with real-time seismic data and ask them to role-play scientists analyzing foreshocks. Have them critique anecdotal claims by comparing them to probabilistic forecasts from monitoring networks.
