Earthquakes: Causes and Measurement

Active learning engages students physically and cognitively with the forces behind earthquakes, making abstract concepts like seismic waves and fault mechanics tangible. By modeling real-world processes, students move beyond memorization to explain why and how earthquakes occur and their impacts on communities.

Activity 01

• Mock Trial
• 50 min · Whole Class

Mock Trial: The Flooding Blame Game

Following a simulated flood event, students take on roles such as the Environment Agency, local farmers, property developers, and residents. They must argue who is responsible for the damage and who should pay for future defenses.

Explain how seismic waves are generated and measured during an earthquake.

Facilitation Tip

For the Mock Trial, assign roles clearly and provide a simple evidence sheet so students focus on applying geological knowledge rather than debating personalities.

What to look for

Provide students with a simplified seismograph reading showing P-wave and S-wave arrival times. Ask them to calculate the time difference between the waves and explain what this difference indicates about the earthquake's distance from the seismograph.

Activity 02

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: Social Media vs. Official Warnings

Students compare a Met Office weather warning with a viral social media post about an upcoming 'weather bomb.' They discuss the dangers of misinformation and how to communicate risk effectively to different age groups.

Compare the Richter and Mercalli scales for measuring earthquake intensity.

Facilitation Tip

During Think-Pair-Share, model how to distinguish between emotional social media posts and factual official warnings by sharing a real example of each before students begin.

What to look for

Present students with descriptions of two different earthquake scenarios: one with a high Richter magnitude but low observed damage, and another with a lower magnitude but significant destruction. Ask: 'Which earthquake would be described as more intense, and why? How do the Richter and Mercalli scales help us understand these differences?'

Activity 03

• Inquiry Circle
• 40 min · Small Groups

Inquiry Circle: UK Weather Records

Groups are given data sets of UK temperature and rainfall from the last 100 years. They must identify trends and 'extreme' outliers, then link these outliers to specific historical weather events they have studied.

Analyze the relationship between fault lines and earthquake occurrence.

Facilitation Tip

In Collaborative Investigation, assign each group one record (e.g., rainfall, temperature, flood level) and ask them to present a one-minute summary to the class before compiling findings.

What to look for

On an index card, ask students to draw a simple diagram illustrating the relationship between a fault line, the focus, and the epicenter of an earthquake. They should label each component and write one sentence explaining how fault movement causes seismic waves.

A few notes on teaching this unit

Teach this topic by starting with students’ prior experiences of minor tremors or news reports, then connect those moments to the science of plate boundaries and stress build-up. Avoid overloading students with jargon; instead, use analogies like a bent stick snapping to explain energy release. Research shows students grasp wave behavior better when they first feel vibrations through a simple table-top experiment before analyzing seismograph traces.

Students will confidently identify the causes of earthquakes, interpret seismograph data, and compare measurement scales to explain variations in earthquake effects. They will also articulate the limitations of early warning systems and hazard assessments in the UK context.

Watch Out for These Misconceptions

• During Mock Trial: The Flooding Blame Game, watch for students assuming that the most expensive damage equals the worst hazard.

  Use the trial’s evidence board to redirect students: ask them to compare flood depth maps, rainfall records, and evacuation notices to identify that infrastructure vulnerability amplifies natural hazard effects.

• During the dice-rolling simulation in Collaborative Investigation, watch for students interpreting '1 in 100 year flood' as a one-time event.

  Pause the simulation and ask students to plot their results on a timeline, highlighting clusters of high rolls to demonstrate that probabilities are recurring, not scheduled.
