Overview
This guided inquiry worksheet takes students through the mechanics of earthquakes — from the movement of tectonic plates to the propagation of seismic waves. Students analyse real seismograph data and use evidence to explain patterns in earthquake distribution.
Learning Objectives
- Describe how P-waves and S-waves differ in their movement and speed
- Explain the relationship between plate boundaries and earthquake locations
- Analyse seismograph data to determine earthquake epicentres
- Evaluate the reliability of earthquake prediction methods
Structure
The worksheet is divided into three sections:
Section A: What happens during an earthquake? Students use diagrams and descriptions to build understanding of fault types and wave propagation.
Section B: Data analysis Students work with real seismograph readings from the USGS database to triangulate an earthquake epicentre.
Section C: Can we predict earthquakes? An evaluation task where students assess different prediction methods and form an evidence-based conclusion.
MYP Alignment: This task targets Criterion B (Inquiring and Designing) with emphasis on formulating testable hypotheses and analysing data.
