Activity 01
Stations Rotation: Seismic Sleuths
Stations provide seismograph readings, P-wave and S-wave arrival time data, and a blank map. Groups use triangulation to locate a simulated earthquake's epicenter, recording their calculation steps at each station before comparing results across groups and discussing sources of error.
Explain what forces deep inside the Earth cause the crust to move.
Facilitation TipDuring Station Rotation: Seismic Sleuths, place one adult or capable student at each station to coach peers in reading seismograms and locating epicenters accurately.
What to look forProvide students with a world map showing major earthquake and volcano locations. Ask them to draw lines representing plate boundaries and label them as convergent, divergent, or transform. Then, have them explain in one sentence why these features are concentrated along their drawn boundaries.

Activity 02
Inquiry Circle: Volcano Types Comparison
Groups receive data sheets on three volcano types (shield, stratovolcano, cinder cone) and create a comparison matrix of eruption style, magma viscosity, typical tectonic location, and hazard level. Groups then argue which type poses the greatest risk to a hypothetical nearby city and defend their reasoning.
Analyze the relationship between plate boundaries and the distribution of volcanoes and earthquakes.
Facilitation TipFor Collaborative Investigation: Volcano Types Comparison, assign each group a different volcano type to research and prepare a 2-minute visual presentation for the class.
What to look forOn an index card, ask students to write the definition of one key vocabulary term and then describe one specific hazard associated with either a volcano or an earthquake, naming a real-world location where this hazard is a concern.

Think-Pair-Share: Should We Build Here?
Show a topographic map with a city positioned near a dormant volcano and known active fault lines. Pairs evaluate the hazards present, then argue a position on whether the city should restrict expansion toward or away from the risk zones, citing specific evidence.
Predict the potential hazards associated with different types of volcanic eruptions.
Facilitation TipUse Think-Pair-Share: Should We Build Here? to have students analyze a real seismic or volcanic risk map before sharing their reasoning with peers.
What to look forPose the question: 'If you were a scientist studying a newly discovered active volcano, what three types of data would you prioritize collecting to understand its potential eruption hazards and why?' Facilitate a class discussion where students justify their choices based on magma type, gas content, and geological setting.

Gallery Walk: Before and After Eruption
Post paired satellite images of volcanic sites before and after major events, including Mount St. Helens 1980 and Kilauea 2018. Groups annotate what changed at each site and infer the eruption type and dominant hazard from the visible evidence.
Explain what forces deep inside the Earth cause the crust to move.
Facilitation TipDuring Gallery Walk: Before and After Eruption, ask students to annotate photos with labeled hazards and protective measures they observe in each image.

Generate Complete Lesson→A few notes on teaching this unit
Start with students’ lived experiences by asking if they’ve heard earthquake or volcano reports, then connect those events to plate tectonics. Use analogies students know, like toothpaste squeezing from a tube, to explain magma flow. Avoid over-simplifying by showing multiple real-world examples of each hazard type so students see the full range of risks.
Successful learning looks like students confidently linking tectonic plate interactions to specific seismic and volcanic events, explaining hazard variations by location and magma type, and using evidence to support decisions about human settlement near geologic hazards.
Watch Out for These Misconceptions
During Station Rotation: Seismic Sleuths, watch for students who assume seismographs only record large quakes. Redirect by showing seismograms from small local tremors and distant major events.
Use the station’s real seismogram samples to point out amplitude scales and explain how even small quakes register, and why location matters more than size for immediate hazard.
During Collaborative Investigation: Volcano Types Comparison, watch for students who generalize that all eruptions are violent. Redirect by having groups present their volcano type’s typical eruption style and lava flow speed.
Prompt groups to compare viscosity and gas content data for their assigned volcano type and explain how these factors control explosivity and hazard type.
During Gallery Walk: Before and After Eruption, watch for students who assume volcanic landforms only exist near plate edges. Redirect by including a Yellowstone caldera image in the gallery.
Ask students to find the Hawaiian hot spot location on the map and compare it to plate boundary maps to recognize that volcanic chains can form far from edges.
