Students investigate why earthquakes and volcanoes cluster in specific zones where Earth's crustal pieces meet. Through analyzing seismic data from real earthquakes or investigating volcano eruption patterns, building models demonstrating divergent, convergent, and transform boundaries using graham crackers and frosting, and engineering earthquake-resistant structures or early warning systems, students discover how plate tectonics drives Earth's most dramatic geological events.
- Lesson 1

Solve: A Rumbling Earth Mystery + Vocabulary Mind Map
Every cake at the Cake County contest is destroyed by an earthquake—except Leonardo's, which he claims proves there was no earthquake at all. Students follow Mosa as she investigates earthquake damage patterns across the county and consults a volcanologist 100 miles away. By the end, they discover that earthquakes and volcanoes share a common cause: the gradual buildup of pressure between slowly moving tectonic plates that suddenly releases energy.
- Lesson 2

Make: Lab Stations: Tectonic Plates Interacting
Four hands-on stations with graham crackers as tectonic plates and Cool Whip (dyed red) as magma. Students model convergent boundaries (plates crash together, mountains form), divergent boundaries (plates pull apart, magma rises), transform boundaries (plates slide past, earthquakes happen), and subduction zones (one plate dives under another, volcanoes erupt). Mini marshmallow "houses" ride on top so students can see what happens to structures during each interaction. Data collection reveals which boundary types create earthquakes, volcanoes, or both.
- Lesson 3

Engineer: Engineer a Solution to Protect People from the Effects of Earthquakes or Volcanoes.
Design protection for a village threatened by either earthquakes or volcanic eruptions. Students research mitigation strategies (earthquake-resistant building designs, lava diversion channels, early warning systems, evacuation routes), choose one natural hazard, engineer a solution, and build prototypes using paper, tape, and various construction materials. Presentations explain how their designs reduce damage and save lives—applying geological knowledge to real-world hazard preparedness.
