Students explore the origin and nature of earthquakes. They view an introductory video which demonstrates the measurement of earthquake strength, and ways buildings are constructed to lessen impact. Students then enter a create phase in which they build a LEGO earthquake simulator, program it, and test it on their own LEGO building designs. They observe results, modify their designs, then compare their results with other class teams. In the final share phase, students document their projects, collect data and present their results. They reflect on their conclusions about the connections between earthquake magnitude and building strength.
